feat: VocaHQ parity (output polish, power controls, settings shell) (#207)

* docs: add VocaHQ parity plan from VocaLinux v0.15

Capture the Mac gap matrix and phased port plan (settings sidebar +
search, auto-pause, idle unload, dictation polish) and point
ARCHITECTURE cross-platform notes at VocaLinux / VocaHQ.

* feat: add dictation polish, auto-pause, and idle model unload

Port VocaLinux output polish (#554/#608) and power controls (#592):
trailing space + auto-capitalize before inject, AutoPauseMonitor,
ModelKeepAlive, sleep/wake recovery, and SpeechTranscribing.unloadModel.

* feat: searchable sidebar settings and expanded language catalog

Replace TabView settings chrome with NavigationSplitView, live search,
and a status/Test Dictation footer. Expand the transcription language
catalog with a searchable picker and update the VocaHQ parity matrix.

* fix: keep recording overlay controls in Application settings search

Co-authored-by: Jatin K Malik <jatinkrmalik@users.noreply.github.com>

* fix: polish settings shell, About layout, and recording overlay

Fix Tahoe NavigationSplitView About breakage via safeAreaInset footer,
improve Test Dictation feedback, slim Speech Model IA, add Stats Share,
bury menu-bar Setup Wizard, and replace overlay cancel/red-dot with the
Voca mark.

* fix: avoid assigning computed averageWPM in share card test

Co-authored-by: Jatin K Malik <jatinkrmalik@users.noreply.github.com>

* ui: polish share card, Advanced pills, test dictation, overlay glow

Dark branded stats share image, compact Advanced resource columns,
Settings Test Dictation without inject, sidebar search/logo consistency,
and a pulsing VocaMac-green glow around the recording overlay.

* ui: match System Settings sidebar search placement

Remove the fake VocaMac sidebar row, drop toolbar .searchable, and pin a
System Settings–style Search field to the top of the sidebar column so
collapse no longer shifts search into the detail toolbar.

* ui: adaptive overlay theme, sensitive waveform, slide-in

Respect system light/dark appearance with high-contrast surfaces,
boost waveform sensitivity for quiet speech, and animate the pill
in from the top/bottom edge based on overlay position.

* ui: pin settings sidebar toggle to the top-right

Replace NavigationSplitView's relocating system sidebar button with a
custom trailing toolbar control and hide the default toggle on macOS 15+.

Co-authored-by: Jatin K Malik <jatinkrmalik@users.noreply.github.com>

* fix: replace NavigationSplitView to stop duplicate sidebar toggles

Use a manual sidebar + detail layout with a single top-right toolbar
button so Tahoe no longer injects relocating left/right system toggles.

* feat: surface model load status for auto-pause and idle unload

Show loaded/unloaded state with estimated RAM in Performance, track
unload reason and approx freed RSS, and explain auto-pause clearly in
the menu bar popover.

Co-authored-by: Jatin K Malik <jatinkrmalik@users.noreply.github.com>

* ui: use brand teal for hot mic and yellow for processing

Align menu bar mark, popover status, and overlay processing colors with
the trademark teal recording state instead of red/purple.

Co-authored-by: Jatin K Malik <jatinkrmalik@users.noreply.github.com>

* chore: scrub em dashes and tighten user-facing copy

No behavior changes. Clean up strings and docs added in this branch so
the UI does not read like generated filler.

Co-authored-by: Jatin K Malik <jatinkrmalik@users.noreply.github.com>

* docs: refresh VOCAHQ_PARITY.md to match shipped #207 UX

Correct sidebar implementation notes, footer behavior, Performance vs
Advanced placement, resolved open questions, and follow-up items.
