v0.47.0: dialogs, session menu, /skills, mobile fixes, mobile QA suite

* fix: custom provider with slash model name no longer rerouted to OpenRouter (#255)

When base_url is configured in config.yaml, resolve_model_provider() now
trusts the configured provider/base_url entirely and skips the slash-based
OpenRouter heuristic. Fixes google/gemma-4-26b-a4b with provider:custom
being silently routed to OpenRouter, resulting in 401 errors.

Fixes #230

* test: mobile layout regression suite — 14 tests for every QA run (#254)

Adds tests/test_mobile_layout.py with 14 static regression tests that run
on every QA pass to catch mobile layout breakage before it reaches prod.
Covers: breakpoints at 900px/640px, right panel slide-over CSS, mobile
overlay, bottom nav, files button, profile dropdown z-index, chip overflow,
workspace close, 100dvh, 44px touch targets, 16px font-size on textarea.

* feat: /skills slash command lists and filters available Hermes skills (#257)

Adds /skills [query] command to commands.js. Fetches from /api/skills,
groups by category (alphabetically sorted), displays as a formatted
assistant message. Optional query filters by name, description, or category.
i18n keys added for en, de, zh, zh-Hant. 1 regression test added.

Fixes #248

* feat: shared app dialogs replace native confirm()/prompt() calls (#251)

Adds showConfirmDialog() and showPromptDialog() helpers to ui.js, backed
by a themed #appDialogOverlay. Replaces all 11 native browser confirm/prompt
call sites across panels.js, sessions.js, ui.js, workspace.js.

Supports: danger mode, keyboard focus trap (Tab/Escape/Enter), focus restore,
ARIA roles, mobile-responsive stacked buttons at 640px. i18n for en/de/zh/zh-Hant.
5 new tests in test_sprint33.py verify markup, CSS, helpers, and absence of
native dialog calls.

Extracted from PR #242.

* fix: Android Chrome mobile — workspace panel close + profile dropdown (#256)

Fix #247: toggleMobileFiles() now shows/hides the mobile overlay when
toggling the right workspace panel. New closeMobileFiles() helper closes
the panel with correct overlay state tracking. Overlay onclick calls both
closeMobileSidebar() and closeMobileFiles(). Mobile-only close button (x)
added to workspace panel header.

Fix #246: profile dropdown uses position:fixed;top:56px;right:8px at
max-width:900px, escaping the overflow-x:auto stacking context that was
clipping it on Android Chrome.

Fix applied during review: closeMobileSidebar() now checks if the right
panel is still open before hiding the overlay, preventing the overlay from
disappearing when only the sidebar is closed.

Fixes #247 Fixes #246

* feat: session ⋯ action dropdown replaces per-row buttons (#252)

Replaces the 5 per-row hover action buttons (pin/move/archive/duplicate/trash)
with a single ⋯ trigger that opens a positioned dropdown menu. Menu has full
keyboard (Escape), click-outside, scroll, and resize-reposition handling.
Position:fixed prevents sidebar clipping.

5 actions: Pin/Unpin, Move to project, Archive/Unarchive, Duplicate, Delete
(danger style). Each with icon and descriptive subtitle.

Updated test_sprint16.py: test_sessions_js_uses_action_menu_not_per_row_buttons
asserts the new trigger and menu functions exist, old per-row classes are gone.

Extracted from PR #242.

* docs: v0.47.0 release notes, bump version, update test counts (645)

+### Features
+- **`/skills [query]` slash command** (PR #257): Fetches from `/api/skills`, groups results by category (alphabetically), renders as a formatted assistant message. Optional query filters by name, description, or category. Shows in the `/` autocomplete dropdown. i18n for en/de/zh/zh-Hant. 1 regression test added.
+- **Shared app dialogs replace native `confirm()`/`prompt()`** (PR #251, extracted from #242 by @aronprins): `showConfirmDialog()` and `showPromptDialog()` in `ui.js`, backed by `#appDialogOverlay`. Replaces all 11 native browser dialog call sites across panels.js, sessions.js, ui.js, workspace.js. Full keyboard focus trap (Tab/Escape/Enter), ARIA roles, danger mode, focus restore, mobile-responsive buttons. i18n for en/de/zh/zh-Hant. 5 new tests in `test_sprint33.py`.
+- **Session `⋯` action dropdown** (PR #252, extracted from #242 by @aronprins): Replaces 5 per-row hover buttons (pin/move/archive/duplicate/delete) with a single `⋯` trigger. Menu uses `position:fixed` to avoid sidebar clipping. Full close handling: click-outside, scroll, Escape, resize-reposition. `test_sprint16.py` updated to assert the new trigger exists and old button classes are gone.
+
+### Bug Fixes
+- **Custom provider with slash model name no longer rerouted to OpenRouter** (PR #255): `resolve_model_provider()` now returns immediately with the configured `provider`/`base_url` when `base_url` is set, before the slash-based OpenRouter heuristic runs. Fixes `google/gemma-4-26b-a4b` with `provider: custom` being silently routed to OpenRouter (401 errors). 1 regression test added. Fixes #230.
+- **Android Chrome: workspace panel now closeable on mobile** (PR #256): `toggleMobileFiles()` now shows/hides the mobile overlay. New `closeMobileFiles()` helper closes the right panel with correct overlay tracking. Overlay tap-to-close calls both `closeMobileSidebar()` and `closeMobileFiles()`. Mobile-only `×` close button added to workspace panel header. Fix applied during review: `closeMobileSidebar()` now checks if the right panel is still open before hiding the overlay. Fixes #247.
+- **Android Chrome: profile dropdown no longer clipped on mobile** (PR #256): `.profile-dropdown` switches to `position:fixed; top:56px; right:8px` at `max-width:900px`, escaping the `overflow-x:auto` stacking context that was making it invisible. Fixes #246.
+
+### Tests
+- **Mobile layout regression suite** (PR #254): 14 static tests in `tests/test_mobile_layout.py` that run on every QA pass. Covers: CSS breakpoints at 900px/640px, right panel slide-over, mobile overlay, bottom nav, files button, profile dropdown z-index, chip overflow, workspace close, `100dvh`, 44px touch targets, 16px textarea font.
