feat(halon): replace TAMTheme with Halon, pulled from its own repository

The theme now lives in github.com/BeatLink/Halon and is built there from the
same token set as its GTK, Cinnamon, Qt, VS Code and terminal implementations,
so this addon vendors no copy: the stylesheet note points straight at
trilium/halon.css, pinned to a Halon commit. A published manifest carries an
absolute sourceUrl through untouched and hashes it by its URL rather than its
content, so moving the pin is also what tells TAM there is an update to fetch —
a branch URL would be silently frozen. bump-halon moves it, refusing to write a
commit that does not actually serve the file.

Rebuilding against Halon's specification changed the look in four visible ways:
the navigation frame is the recessed light surface rather than dark navy, so
the theme no longer forces a third on-colour; buttons regain all three weights
instead of every one being an accent ghost; there is no softened accent, so a
row you pick is the accent itself; and dark-mode fills carry dark text, which
is what the palette was always audited for.

The id changes with the name, so TAM cannot match an existing install: this is
an install-and-remove, not an update. The README says so.

 | [Game Tracker](addons/game-tracker@beatlink/) | widget | A video game tracker for TriliumNext. Your whole library lives in one JSON note created under a library root you choose, so it is a single note you can back up, inspect, or hand-edit. Pick any note as the Library Root and the addon wires it up for you: it becomes a render note showing the tracker, and switching roots reverts the old one. Metadata comes from an ordered list of seven sources -- IGDB, RAWG, Steam, GOG, Lutris, SteamGridDB, and TheGamesDB -- merged FIELD BY FIELD rather than picked one at a time: the first source supplying a value wins that field, and anything it leaves empty falls through to the next, so one game can carry IGDB's platforms, SteamGridDB's cover, and Steam's summary. Reordering changes precedence and untick disables. Three sources (Steam, GOG, Lutris) need no API key at all, so the tracker works with zero setup even where Twitch's two-factor requirement makes IGDB unobtainable. The chain stops as soon as every field is filled, so sources placed lower are only consulted for genuine gaps -- which is how the quota-limited TheGamesDB stays cheap at the end of the order. Each source records which fields it supplied, so provenance is visible per game. The composite is used everywhere metadata is read, not just on import: the library refresh re-merges every enabled source rather than only the first, and the details page is composed the same way -- addressing each source by its own recorded id, the Steam appid, or the title -- so a game with no IGDB id, including a Steam-only or file-imported one, opens and refreshes exactly like any other. Steam is a one-way import source for owned games and playtime, read but never written to; on IGDB, Steam appids are resolved in bulk through the external_games index so a whole library matches in a handful of requests. A library file can also be imported directly: an IGDB GDPR data export, or any CSV/JSON list of games. Because such files carry only titles, every row is matched by name and the result is previewed -- matched, unmatched, and already-tracked counts, with the provider's own spelling shown -- before anything is written. Statuses are fully user-defined -- add, rename, recolour, reorder, or remove them on the Statuses tab. Each status carries a role (backlog / playing / done / abandoned / none) and imports target the role rather than the name, so renaming Beaten to Finished, or adding a Wishlist alongside Backlog, never breaks an import. A game stores a status id, so renaming one touches no data, and removing a status leaves every game still holding it untouched rather than silently reclassifying it. Imports are additive and idempotent: games are keyed by their strongest known id and matched on any shared id so every source converges on one entry, playtime never moves backwards, and your own ratings and status are never overwritten unless you opt in. Nothing is ever marked Beaten by a Steam import -- playtime cannot tell whether a game was finished, so that stays your call. Each import reads the database once and writes once, so it cannot half-apply. Modelled on media-tracker@beatlink, which tracks films and TV. | 1.4.0 |

TMDB provides search, posters, and episode lists; Trakt and Stremio are one-way import sources, read but never written to. Per-episode progress for shows is a compact run-collapsed string (s01e01-e10,s02e01) rather than a list of every episode, so a fully-watched ten-season show stays a short value.

Subscribe to RSS, Atom, RSS 1.0 and JSON feeds and read them in one list, or point it at a FreshRSS server and get its feeds, folders, articles and read/starred state, with your changes pushed back through the Google Reader API it exposes. Sync is two-way: marking read or starring here reaches the server immediately, subscribing and unsubscribing happen on the server, and a change that fails to push is queued and retried on the next sync. Feeds, articles and state live in one JSON note you can back up, inspect, or hand-edit. Feed bodies are stripped of scripts and other executable markup before they are rendered. Fetching goes through a backend note, since a feed sends no CORS headers, so Trilium's backend scripting has to be enabled; there is no background sync, because parsing a feed needs the browser's XML parser and refreshes therefore happen while the widget is open. | 1.2.0 |

Ships nine bundled template notes under its own persisted Templates container: eight item types (Ideas / Goal / Routine / Task / Future / Project / Note / Link, the last a Web View note carrying #webViewSrc and #url for a saved web page) and the AreaCollection container template, meant for per-area root notes rather than as an item's own type. It also ships one empty root container note per bundled item template (Ideas / Goals / Routines / Tasks / Future / Projects / Notes / Links), carrying only the template's icon and #viewType=list; as of 1.13.0 they sit beside the templates in the Templates container instead of under the AreaCollection template, so a new Area no longer comes out holding copies of them. Each registry row has a Root Note field so other addons can resolve a template's root. | 1.17.0 |

An editable label above the controls names what is being timed. Optional select/start/end sounds ship with the addon as customResourceProvider files and are toggled by the addon's single setting. Split out of agenda-myday@beatlink, which used to embed it in the My Day panel: it shares no code or config with the agenda addons and works on its own. | 1.2.1 |

+# Halon
+
+A slate and blue theme for Trilium, built on the TriliumNext `next` base. Navigation chrome — the
+launcher rail, the tab bar, the toolbars — sits one step *back* from the content it wraps, and the
+thing you have selected is a raised card rather than a block of colour. Structure comes from
+hairline borders and a three-step surface scale; shadows appear only where something genuinely
+floats. One blue accent carries links, focus and the primary action, and nothing else.
+
+It ships a matching dark mode and follows your operating system's colour scheme, as the `next` base
+it sits on does.
+
+Halon is a whole-desktop theme, not only a Trilium one. The same token set drives its GTK, Cinnamon,
+Qt, VS Code, Firefox, Tilix, LMMS, LightDM and Plymouth implementations, so Trilium matches the rest
+of the session. Every foreground and background pair it specifies meets WCAG 2.1 AA in both schemes.
+
+## Install
+
+Install through the Addon Manager, then pick **Halon** under Options → Appearance → Theme.
+
+The stylesheet note carries the two labels the theme needs, so there is nothing to set by hand:
+
+```
+#appThemeBase=next   #appTheme=Halon
+```
+
+## Where the stylesheet comes from
+
+This addon does not keep its own copy of the CSS. Its stylesheet note points straight at
+`trilium/halon.css` in the [Halon repository](https://github.com/BeatLink/Halon), pinned to a
+commit, so the theme here and the theme everywhere else cannot drift apart. The design guide, the
+token set and the contrast audit all live there.
+
+## Previously
+
+This addon replaces **TAMTheme** (`tamtheme@beatlink`), which was the same theme under its earlier
+name and before it was rebuilt against Halon's specification. The visible changes are a light-mode
+navigation frame in place of the dark navy one, the three button weights, and a dark mode whose
+fills carry dark text rather than white. TAMTheme is not updated in place — install this and remove
+the old addon.
