Remove dialogue tone-of-voice system, add Gitea Actions full build, add venue cycling

- Delete Rules.Tone/TONE_NAMES, NpcProfile.tone_modifiers, tone params on
  NPCController.roll_reaction/apply_player_action; dialogue_lines flattened
  to Array[String]; HUD tone label, T binding, and hud.tone_prefix removed
- Docs updated everywhere (PLAN, README, DONE, MEMORY); PLAN section heading
  'Tone and Design Direction' -> 'Design Direction'
- Add .gitea/workflows/build.yml: checks job (import+tests) on push/PR; full
  build job (export templates, Linux/Windows/macOS exports, artifact upload,
  and tag-based Gitea release publish via GITEA_TOKEN) on tags/dispatch
- Remove old .github/workflows/ci.yml to avoid double runs
- Add venue cycling (V) across all three scenarios with hud.venue_switched
- Refresh README screenshots to match the new HUD
- 53/53 tests pass, boot smoke clean

 - Perception pass: `NPCController.perceive_guard(distance)` returns `{noticed, band, reaction}` with bands `unaware` (>6m), `aware` (2-6m), `near` (<2m). Near + temperament ≥0.6 → ARGUE, else COMPLY. `GameManager._perception_pass()` feeds real guard distance each physics tick and logs first-time notice.
 - Responder dispatch: `RadioSystem` tracks `pending_calls` and decrements `arrival_delay_s` in `tick`; emits `responder_arrived` when a call's delay elapses. `RadioSystem.responder_outcome(call)` maps danger/weapons → command/restraint/evacuation/arrest. `GameManager._on_responder_arrived` spawns a `RESPONDER` avatar at the entrance and logs the outcome. HUD shows an emergency-radio cooldown label via `_update_radio_cooldown`.
 - Wand screening (Joke Shop): `WandScreener` (new `src/core/wand_screener.gd`) classifies carried items as prohibited (`weapon/knife/gun/blade`) vs false-alarm (`keys/belt/phone/coins/watch/buckle`) vs clear. `NpcProfile.carried_items` holds guest items. `GameManager` binds `W` to `_toggle_wand_screening` and `A`/`D` to `decide_wand`; `decide_access` blocks admission at wand venues until `controller.screened` is true. `VenueScenario.door_staff_lines` holds venue-specific door-staff dialogue (Joke Shop has id/ticket/wand/refusal/prohibited lines).
-- Polish/accessibility: tone picker (`T` cycles `selected_tone` via `TONE_ORDER`; HUD `tone_label`), aim-free targeting (`Tab` cycles nearby NPCs within `NEARBY_RADIUS`), color-coded escalation indicator (`Hud.set_escalation`), procedural audio (`AudioFeedback` node generates sine tones for confirm/radio/escalation/deny), and a centralized `Strings` table (`src/core/strings.gd`, `lookup`/`fmt`) for localization. NOTE: `Strings.get` was renamed to `Strings.lookup` because `get` collides with `Object.get`.
+- Design change (2026-10-31): the selectable dialogue tone-of-voice system was **removed**.
+  `Rules.Tone`/`TONE_NAMES`, `NpcProfile.tone_modifiers`, and the tone param on
+  `NPCController.roll_reaction/apply_player_action` no longer exist; `NpcProfile.dialogue_lines`
+  is a flat `Array[String]`; `GameManager` uses `_apply_interaction(level, action_name)`;
+  the `T` key is gone. HUD `tone_label` removed and `hud.tone_prefix` string deleted from JSON.
+- Polish/accessibility: venue cycling (`V` cycles `VENUE_ORDER` and restarts the shift), aim-free
+  targeting (`Tab` cycles nearby NPCs within `NEARBY_RADIUS`), color-coded escalation indicator
+  (`Hud.set_escalation`), procedural audio (`AudioFeedback` node generates sine tones for
+  confirm/radio/escalation/deny), and a centralized `Strings` table (`src/core/strings.gd`, `lookup`/`fmt`)
+  backed by `content/strings.en.json`. NOTE: `Strings.get` was renamed to `Strings.lookup` because
+  `get` collides with `Object.get`.
 - Newly added: LATE shift phase (start 700s) with a reachability test; PROTESTER archetype + events + colors; CALL_SOMEONE reaction; `DoorState` core class + `L` binding + visual indicator; flashlight (`G`, SpotLight3D, perception bonus at evening/late); persistence wired (`Save.save_shift_result` on shift end, history + best score on the review screen); `NavigationRegion3D` flat navmesh + `NavigationAgent3D` NPC paths (steps now visual-only); strings moved to `res://content/strings.en.json` (41 keys, loader keeps `lookup`/`fmt`); `export_presets.cfg` (Linux/Windows/macOS) + `tools/build_releases.sh` + `docs/RELEASING.md`; README Downloads section.
 - Run tests: `godot --headless --path . --script res://src/test/test_runner.gd`
 - Boot check: `godot --headless --path . --quit-after 120`
 - Screenshot tools: `godot --path . -s res://src/test/take_screenshot.gd` (single shot to `user://screenshot.png`); `godot --path . -s res://src/test/capture_screenshots.gd` (staged README gallery shots to `user://screenshots/`, copied to `docs/screenshots/`).
 - Release build verified locally: export templates for 4.3 installed at `~/.local/share/godot/export_templates/4.3.stable/`; `./tools/build_releases.sh` produced Linux/Windows/macOS artifacts for 0.1.0 in `build/` and the Linux binary passed a headless smoke test. Publishing to Gitea still needs a token (see `tools/publish_release.sh`, `docs/RELEASING.md`).
+- CI: the repo now carries a **Gitea Actions** workflow at `.gitea/workflows/build.yml` (checks on
+  push/PR; full export + artifact upload + optional release publish on tags and `workflow_dispatch`).
+  A repo secret `GITEA_TOKEN` is required for tag releases. The old `.github/workflows/ci.yml` was
+  removed so hosts scanning both paths do not double-run.
+- Venue cycling: `V` switches Hollywood Blvd → The Joke Shop → TV Studio and restarts the shift.
