docs: audit and refresh user-facing and internal docs

Cross-check every config key, shortcut, default, and command against the
current source and fix the drift (mpv.socketPath, auto_start_overlay
default, AniSkip TAB key, JLPT N4 color, secondary-sub font/defaults,
secondary-sub language behavior, modular mpv plugin layout, and more).
Add plain-language intros and first-use definitions across onboarding and
integration pages so non-technical readers can follow along.

Internal docs/: fix stale module paths in architecture/domains.md, add
missing contract entry points and catalog rows, and bump verified dates.
Remove the obsolete docs/plans/ directory (its only plan shipped in
0.15.0) and reframe planning.md so plans live with the work, not in docs/.

# MPV Plugin
The SubMiner mpv plugin (`subminer/main.lua`) provides in-player keybindings to control the overlay without leaving mpv. SubMiner-managed launches inject the bundled runtime plugin, so users do not need to install it into mpv's global `scripts` directory.
**What this is:** mpv is the video player SubMiner overlays subtitles on. The SubMiner mpv plugin is a small Lua script that runs *inside* mpv and gives you in-player keybindings to control the SubMiner overlay (start/stop/toggle, skip intro, etc.) without leaving the player window.
**Who needs this page:** Most users never touch the plugin directly — SubMiner-managed launches (the app, the `subminer` launcher, or the Windows shortcut) inject the bundled plugin automatically for that session, so there is nothing to install into mpv's global `scripts` directory. Read on if you launch mpv from another tool and want SubMiner's in-player controls, or you want to script mpv against SubMiner.
The plugin ships as a modular Lua package under `plugin/subminer/` (entry point `init.lua`, which loads `main.lua` and sibling modules). Earlier releases shipped a single global `main.lua`; runtime loading replaces it.

## Keybindings
All keybindings use a `y` chord prefix — press `y`, then the second key:
Most plugin actions use a `y` chord prefix — press `y`, then the second key (a "chord"):
| Chord | Action |
| ----- | ---------------------- |
| `y-y` | Open menu |
| `y-s` | Start overlay |
| `y-S` | Stop overlay |
| `y-t` | Toggle visible overlay |
| `v` | Toggle primary subtitle bar visibility |
| `y-o` | Open settings window |
| `y-r` | Restart overlay |
| `y-c` | Check status |
| `y-k` | Skip intro (AniSkip) |
| Chord | Action |
| ---------------- | -------------------------------------- |
| `y-y` | Open menu |
| `y-s` | Start overlay |
| `y-S` | Stop overlay |
| `y-t` | Toggle visible overlay |
| `y-o` | Open settings window |
| `y-r` | Restart overlay |
| `y-c` | Check status |
| `y-h` | Open session help / keybinding modal |
| `v` | Toggle primary subtitle bar visibility |
| `TAB` (default) | Skip intro (AniSkip) |
The AniSkip key is **not** a `y` chord. It defaults to `TAB` and is configurable via `mpv.aniskipButtonKey`. The legacy `y-k` chord still works as a fallback unless you remap the AniSkip key onto it.
The bare `v` binding is a forced mpv binding. It overrides mpv's default primary subtitle visibility toggle and routes the action to SubMiner's primary subtitle bar instead.
## Shared Shortcuts (Session Bindings)
The `y-*` chords above are built into the plugin. Everything else you configure under [`shortcuts.*`](/shortcuts) — plus any custom [`keybindings`](/configuration) and the stats toggle/mark-watched keys — is **injected into mpv at runtime**, so the same shortcut works both inside mpv and in the SubMiner overlay. You do not edit any mpv config to enable them.
How it works:
1. The SubMiner app compiles your configured shortcuts, custom keybindings, and stats keys into a normalized list and writes it to `session-bindings.json` in the SubMiner config directory.
2. On load, the plugin reads that file and registers each entry as a forced mpv key binding, translating each accelerator into the matching mpv key name.
3. When a binding fires, the plugin either runs a SubMiner action (by invoking the SubMiner binary with the corresponding CLI flag, e.g. `--mine-sentence`) or runs a raw mpv command, depending on what the shortcut maps to.
Because the bindings come from the same configuration the overlay uses, you maintain one set of shortcuts for both surfaces.
Live updates: changing a shortcut in the app rewrites `session-bindings.json` and sends the plugin a `subminer-reload-session-bindings` script message, so mpv re-registers the bindings immediately — no mpv restart required.
Notes:
- Accelerators are normalized per platform — `CommandOrControl` resolves to `Cmd` on macOS and `Ctrl` elsewhere.
- Multi-line actions (`copySubtitleMultiple`, `mineSentenceMultiple`) register temporary `1``9` digit follow-up bindings after the trigger key, with `Esc` to cancel.
- If two shortcuts compile to the same key, or an accelerator can't be mapped to an mpv key, the app logs a warning and skips that binding instead of registering a broken one.
