New `camera` module in modules.example.yaml (and the embedded copy) with
four functions: `set` (any control=value list, incl. preset/colour buttons),
`toggle` (flip between two values), `adjust` (step a numeric control by a
delta, clamped to the min/max parsed from `cameractrls -l`, with optional
`extra` controls applied first), and `is` (poll helper, exit 0 on match).
Device comes from CAMERA_DEVICE in .env (default /dev/video0) or a per-key
`device` param. cameractrls exits 0 for unknown controls, so polls must
use `is`; stderr is discarded to drop Python deprecation warnings.
README: Camera module section with setup, function table, a folder
example, and the oksvg viewBox-offset centring gotcha for SVG icons.

A key with `folder: NAME` swaps the deck to the keys defined under
`folders.NAME`. Every folder shows a back key (slot 0 by default, drawn
with a built-in chevron) that pops back to the parent; folders nest.
The daemon now runs one page at a time: per-key setup moved into
setupKey(), openPage() draws a page under its own context, and
page.stop() tears it down before the next page is drawn (and on exit,
so device death no longer waits on uncancelled goroutines).
streamdeck-ctl gains `key set -folder`, reports kind "folder", lists
every folder in status, and refuses to `key press` a navigation-only
key. The Omarchy grid shows a folder glyph.

go-hid's ReadWithTimeout takes a time.Duration, so the bare 250 was
250ns, which truncates to a 0 ms hid_read_timeout. On both Linux
(poll) and macOS (cond_timedwait) 0 ms means non-blocking, so the
button loop spun continuously: ~1.2 cores and ~7.5k context
switches/sec at idle, from startup.
Pass 250*time.Millisecond and match hid.ErrTimeout with errors.Is
ahead of the string fallback. Idle CPU drops to ~0%.

(cherry picked from commit 69d2926a1a)
streamdeck-ctl reports device/daemon/key status as JSON and edits the
config (brightness, key set/clear/press, daemon control) so front-ends
don't have to reimplement YAML handling or device probing.
- internal/config/edit.go: comment-preserving, node-level YAML edits with
atomic writes; key indices written as !!int so config.Load accepts them.
- internal/device: add model names, Lookup() and Present() for probing
without opening the HID handle.

Add "; charset=utf-8" to the JSON Content-Type header so Slack's
users.profile.set no longer returns the missing_charset warning.

Introduce a per-key `text_command` + `refresh` feature: the service
periodically runs a shell command and renders its stdout as the key's
text overlay, compositing over the base icon (or a black background for
text-only keys) each tick. `text` acts as the static fallback shown
before the first run or when the command errors/outputs nothing. A
refresh goroutine owns the key's image and also handles an optional poll
block (choosing icon_true/icon_false per tick). Adds `$(...)` sugar in
`text` as shorthand for `text_command`.
- internal/config: add TextCommand/Refresh fields to KeyConfig
- cmd/streamdeck: refreshTextKey goroutine, runTextCommand, unwrapCmdSubst
- config.example.yaml: document the feature with a `flow` pomodoro
live-countdown example (status --short, toggle/skip/stop/gui)
- modules.example.yaml: example config updates

- Treat "timeout" and "interrupted system call" from ReadWithTimeout as
non-fatal — hidraw on Linux returns errors instead of (0, nil) for
both, causing false device-dead detection and reconnect loops
- Resolve icons_dir relative to the config file when the path is not
absolute, so the service finds icons regardless of working directory
- Installer now copies bundled icons to the config dir on first install
