refactor(main): fold remaining main-deps builders into their handlers (#308)

* refactor(main): drop remaining pass-through main-deps builders

Jellyfin client-info/setup-window/remote, overlay shortcuts/visibility/
layout/window-factory, config hot-reload, and startup bootstrap factory
builders only forwarded deps. Callers now pass deps to the handlers
directly; createWatchConfigPathHandler moves into config-hot-reload-handlers.

* refactor(main): fold small-logic main-deps builders into their handlers

Tray click, mpv client factory, startup bootstrap exit callbacks, overlay
runtime options, and dictionary roots/runtime builders move their logic
into the owning handler or call site. The two duplicated dictionary-root
builders become one createBuildDictionaryRootsHandler(vendorDirName).

* refactor(main): fold cli command context builders into the factory

createCliCommandContextFactory now adapts appState and main services to
the CLI command context deps directly (socket-path change notification,
texthooker port/websocket URL, browser-open default). The pass-through
cli-command-context-main-deps and cli-command-context-deps layers are
removed; their behavioural tests now run against the factory's context.

* refactor(main): fold subtitle tokenization builder into the mpv composer

The tokenizer deps builder's logic (known-word lookup recording and the
character-dictionary gate on name matching) becomes
buildTokenizerRuntimeOptions in mpv-runtime-composer, tested through the
composer. The MeCab check and dictionary prewarm handlers move to
subtitle-tokenization-warmup.ts, and the unused BuiltMainDeps type is
removed from composer contracts.

* refactor(main): drop redundant tokenizer deps keys and cast

* refactor(main): end the main-deps builder pattern

mpv-main-event-main-deps becomes mpv-main-event-binding-deps
(createMpvMainEventBindingDeps), returning the binding deps directly
instead of a thunk; it owns the subtitle-recording state. The will-quit
cleanup adapter likewise returns its deps directly, and the pass-through
app-lifecycle activate builders are removed.

* docs: drop references to main-deps builders
