feat(capture): dictation, personalities, 0.5.0

Ships the Capture release end to end. Global-hotkey dictation with
synthetic paste into the focused app on macOS and Windows, an on-screen
pill across recording / transcribing / refining, customizable push-to-
talk and toggle chords, and an accessibility-permission prompt scoped to
Settings → Captures with inline re-check feedback.

Voice profiles gain optional personalities that power compose / rewrite /
respond actions via a local Qwen3 LLM — shared with refinement, so there
is one local LLM in the app, not two.

Refinement hardened with deterministic Whisper-loop collapse before the
LLM sees the transcript, per-capture flag snapshots for re-runs, and a
ten-transcript evaluation harness across every bundled refinement size.

Version bump 0.4.5 → 0.5.0.

+//! Stable string ↔ `rdev::Key` mapping for chord persistence.
+//!
+//! The frontend captures keypresses through the browser keyboard API (which
+//! exposes `event.code` like `"MetaRight"`, `"AltRight"`, `"Space"`, `"KeyA"`)
+//! and stores chords in capture_settings as JSON arrays of canonical names.
+//! On the way back the same names need to round-trip into `rdev::Key`
+//! variants the chord engine actually matches against.
+//!
+//! Names follow the rdev variant identifiers exactly (`"MetaRight"`,
+//! `"AltGr"`, `"KeyA"`, …) with one alias: the browser reports right-Option
+//! as `"AltRight"` while rdev calls it `"AltGr"`. Both map to the same key.
+
+use rdev::Key;
+
+/// Resolve a canonical key name to its `rdev::Key`. Returns `None` for
+/// names that don't have a corresponding variant — the command surface
+/// rejects those so we never silently drop keys from a chord.
