Fix external monitor brightness OSD

brightnessctl drives the kernel backlight class, which laptop panels
have and this desktop does not -- it reports only keyboard and NIC LEDs.
So BrightnessControl removed itself and there was no way to dim the
screen from Panama at all. DDC/CI is the channel the buttons on a
monitor's bezel drive, and it is the only brightness an external display
has. Both sources now render a row each, so a machine gets whichever it
actually has, or none.

Displays are enumerated from sysfs rather than `ddcutil detect`. The
kernel publishes the connector-to-bus mapping as
/sys/class/drm/<card>-<connector>/ddc along with whether anything is
plugged in, which beats parsing detect's undocumented brief output,
yields the connector name spelled exactly as Hyprland spells it, and
probes only connectors with a monitor attached -- one bus on this
machine rather than fourteen, where each empty bus costs a timeout.
No model name is read: Hyprland already knows what every output is
called, so the UI joins on the connector instead of keeping a second
source of truth that could disagree with the Displays page.

Writes are debounced, serial, and read back. Serial because DDC/CI has
no arbitration and two ddcutil processes on one bus interleave their
exchanges and both return garbage. Read back because a write is not a
promise: panels clamp to their own range, ignore values while waking
from standby, and drop writes that arrive too fast. Without the read the
slider would show what Panama asked for rather than what the monitor
did, which is the same class of lie as trusting `hyprctl keyword`.

Brightness is deliberately not a stored preference. The monitor
remembers it and the bezel buttons change it behind Panama's back, so
persisting it would mean restoring a value the panel had moved past.

The contract runs against fixtures with ddcutil stubbed and both sysfs
roots redirected, so it never touches a real monitor. Its fixture
reports a maximum of 200 rather than 100 on purpose -- at 100 the
scaling arithmetic is the identity and a helper that ignored the
reported maximum would pass everything. Verified it catches that, plus a
dropped connection-status filter and an unstripped connector prefix.

Not yet confirmed against hardware: this machine cannot open any I2C bus
yet. ddcutil's udev rule grants that through uaccess but only to devices
created after it was installed, so it needs one udevadm trigger. The
helper detects exactly that case and returns the command as its error
rather than reporting "no displays".

+## Generated configuration
+
+Two ecosystem tools cannot read the shared settings file, and their configs live
+in this directory — which is a symlink into the Panama repository, so writing to
+them at runtime would put machine state into a tracked file. Both are therefore
+generated elsewhere:
+
+| Tool | Generated to | Pointed there by |
+|---|---|---|
+| `hypridle` | `$XDG_STATE_HOME/panama/hypridle.conf` | a systemd user drop-in installed by `panama-idle install` |
+| `hyprpaper` | not generated — the wallpaper is applied over IPC and re-applied at shell start | — |
+
+`quickshell/scripts/panama-idle` regenerates the hypridle config from the
+settings store and restarts the daemon. `hypridle.conf` in this directory
+remains the shipped default and is what runs when the drop-in is not installed;
+Panama Settings shows which of the two states you are in rather than presenting
+controls that quietly do nothing.
+

+### Adding a keybind: use `bind`, not `hl.bind`
+
+Every bind in `keybinds.lua` goes through a local `bind()` wrapper that
+substitutes the chord from a stored override, so shortcuts can be moved from
+Panama Settings without editing this file.
+
+```lua
+bind(mod .. " + Q", hl.dsp.window.close(), { description = "Close window" })
+```
+
+Only the **chord** is ever taken from settings — the action is always the Lua
+value written here. A stored override can therefore move a shortcut but can
+never make one do something else, which is what makes reading overrides from a
+file the user can edit safe.
+
+Overrides are keyed by the **shipped chord**, not the description. Descriptions
+are not unique: "Calculator" is both `SUPER + C` and the `XF86Calculator`
+hardware key, and keying by description moved both onto the same new chord,
+silently costing the hardware key.
+
+An override whose value is not a plausible chord is ignored in favour of the
+shipped one, so a hand-edited `settings.json` cannot cost you a keymap.
+
 ### Keybind descriptions are required
 
 Every `hl.bind` must pass a `description`. Hyprland reports Lua-defined binds

+# Panama Settings
+
+The control centre for everything Panama owns. Anything the system owns —
+hardware, accounts, printers — is delegated to GNOME Settings and labelled as
+such rather than half-reimplemented.
+
+## Adding a setting
+
+One schema entry. That is the whole job.
+
+```qml
+// config/PreferenceSchema.qml
+{
+    key: "blurSize", type: "int", def: 8, min: 1, max: 20, step: 1,
+    unit: "px", group: "effects",
+    label: "Blur radius",
+    detail: "Larger is softer and costs more frame time",
+    hypr: { path: ["decoration", "blur", "size"], option: "decoration:blur:size", readAs: "int" }
+}
+```
+
+```qml
+// the page
+SliderRow { setting: "blurSize" }
+```
+
+Persistence, validation, clamping, reset, search indexing, and — with a `hypr`
+block — live application to the compositor and the startup replay all derive
+from that entry. There is nothing else to register.
+
+If it is compositor-backed, add the matching `prefs.get("blurSize", 8)` in
+`hypr/looks.lua` so the Hyprland config still stands alone with no settings
+file.
+
+## The rows
+
+| Component | For |
+|---|---|
+| `SettingsPage` | The page scaffold: title, lede, optional pinned `header` |
+| `ToggleRow { setting }` | A boolean |
+| `SliderRow { setting }` | A number; `zeroLabel` renders 0 as "Never"/"Instant"/"None" |
+| `ChoiceRow { setting }` | An enum, as a segmented control |
+| `ActionRow` | A button: opens a GNOME panel, runs a one-shot |
+| `TextRow` | A genuinely read-only fact |
+
+`TextRow` is for facts, not for settings that were merely expensive to wire.
+Before Stage 3 more than half of all rows were static text standing in for
+controls; that is the failure this vocabulary exists to prevent.
+
+Rows write through `SystemSettings.commitPreference(key, value)`, which routes
+compositor-backed keys through apply-and-verify and local keys straight to the
+store. A row never needs to know which kind it holds.
+
+## Things that will bite you
+
+**`readAs` describes the answer, not the setting.** `hyprctl getoption` returns
+the value in a different JSON field per type — `int`, `bool`, `float`, `str`,
+and `css` for gaps (a four-value box). Declaring the wrong one does not fail
+loudly: it makes every write to that key look *rejected*, and the user sees an
+error for a change that worked. `tests/quickshell/schema-hypr-shape-contract.sh`
+asks the compositor for the real shape of every mapped option.
+
+**Never trust an exit code from `hyprctl`.** `keyword` refuses to work on a
+Lua-configured Hyprland, prints the refusal to stdout, and exits 0. `eval` exits
+0 on syntax and runtime errors too. The only trustworthy signal that a write
+landed is reading the value back.
+
+**The Settings window is tiled.** `implicitWidth` is a hint; the layout decides,
+and it ranges from a half-screen split to the full display. `SliderRow` stacks
+its control under the label below 520px. Test narrow.
+
+**Binding an anchor to `undefined` does not reliably release it.** Switching
+layouts that way left a slider anchored to both edges with the label squeezed
+into what was left. Position explicitly instead.
+
+**Inside a `SettingsCard`, `parent` is the card's internal Column.** So
+`parent.modelData` in a nested `Repeater` is undefined and the rows silently
+never appear — you get a card with a heading and nothing under it. Address the
+outer model through an explicit `id`.
+
+**A `TapHandler` declared as a child of `SettingRow` lands in the trailing
+slot**, because that is the row's default property, so only the right-hand edge
+becomes clickable. Use `activatable: true` with `onActivated` for a whole-row
+target.
+
+**A copy of the Quickshell config shares the live shell's ID.** Quickshell
+derives the Shell ID from config *content*, not path, so
+`cp -a config/dot/quickshell $tmp && qs -p $tmp kill` kills the running
+desktop, and `qs -p $tmp ipc call …` can drive it. Harnesses that point at a
+single distinct `.qml` file are safe; copying the whole directory is not.
+
+## Where state lives
+
+| File | Holds |
+|---|---|
+| `~/.config/panama/settings.json` | Everything in the schema. Read by the shell *and* by `hypr/prefs.lua` |
+| `$XDG_STATE_HOME/panama/panama-home.json` | Home accessory favourites and aliases |
+| `$XDG_STATE_HOME/panama/backups/` | Settings snapshots |
+| `$XDG_STATE_HOME/panama/hypridle.conf` | Generated idle config |
+
+`SystemSettings.restoreDefaults()` spans all of them. A reset that silently
+skipped one would be worse than having no reset, because nothing would say so.
+
+## Not stored by Panama
+
+Timezone and network time are read from and written to `timedatectl` directly.
+They belong to the machine and are shared with sessions that never see Panama's
+file; storing a copy would create a second answer to a question the system
+already answers.
