* feat(detect): add muse agent with generic Pick blocked detection

Add Muse agent manifests and runtime detection for idle/working/blocked
states. Blocked Pick is generic on footer 'Enter to select' so any
question title/message triggers, fixing missed waiting answer where
previous AND-gated rule required specific hint combos. Cover process
names muse, muse-bin, muse-code variants and YOLO footer.

* fix(detect): tighten muse manifest and agent lookup

- manifests: change working_esc_interrupt and blocked_approval
  from whole_recent to bottom_non_empty_lines(8) to use captured
  bottom-buffer controls instead of incidental whole-pane text
- manifests: anchor idle_prompt line_regex to ^\s*⟩\s*$ so working
  chrome "⟩ ..." does not match idle
- runtime: restrict muse lookup to explicit aliases
  (muse|muse-bin|muse-code|muse-cli), remove starts_with("muse")
  fallback that misclassified museum/muse-helper/muser; add
  positive/negative identification tests
- keep website mirror identical; verified with agent_detection
  manifest check --require-website

* fix(detect): address mjdouglas vendor findings for muse

- manifests: widen pick_request_blocked to bottom_non_empty_lines(8) and add
  Enter to toggle for multi-select; add menu_request_blocked for user-opened
  pickers (enter confirm/esc go back/esc close/space toggle); add
  workspace_trust_blocked for Do you trust dialog; tighten blocked_approval
  to footer chrome Allow once/Always allow/Yes proceed; split idle_prompt
  into any gate for empty and typed draft and not-gate pick/menu anchors;
  change idle_status_fallback from YOLO to model \u00b7 effort \u00b7 cwd shape
- runtime: replace bare muse-bin alias with muse-bin-<version> digit check
  to match versioned launcher binary and avoid museum/muse-binary false
  positives
- cross-checked with vendor-side captures reported on PR #2489 against
  strings in shipped muse-bin binary

refs #2489

* fix(detect): handle path-qualified muse-bin versioned binary

lookup_agent now uses path_basename before matching so a launcher
exec with absolute argv0 like /usr/local/lib/muse/muse-bin-0.1.0-R708.1
is correctly identified. is_muse_versioned_binary also checks basename
so direct path-qualified names succeed without relying on the
argv0_argv fallback path. Prevents missed Muse detection when screen
state and sound overrides are not applied.

refs #2489

* fix(detect): add enter save to muse menu detection

Evidence documents /theme with enter save footer which was not
matched. Add enter save to menu_request_blocked any list and to
idle_prompt not-gate (highlighted row ⟩ <choice> shares glyph) and
keep website mirror in sync. Update evidence comment counts from
four to five.

refs #2489

* docs: add Muse to supported agents table

Muse detection (manifest, process identification, sound)
was added earlier but docs/next agents table omitted the row.
Add Muse as screen manifest / none (no integration hook,
consistent with Amp/Kiro/Maki) to en/ja/zh-cn translations.

* fix(detect): resize agent arrays for new upstream variant

Agent::ALL and SCREEN_MANIFEST_AGENTS gained an entry from master
but kept stale size annotations, breaking compilation after rebase.

* docs: add muse detection entry to next changelog

refs #2489

* docs: add muse sound override to config reference

refs #2489

* fix(detect): prevent false muse blocked states
