goyban 0732f2c34b Record what may be shared, ahead of federation
The bot-side half of TODO #4. Nothing federates yet; this establishes
what would be eligible to, and proves the boundary before there is a
hub that could leak across it.

- Schema v5 adds visibility, defaulting to private. Upgrading an
  existing library therefore opts nothing into sharing, which a test
  on the legacy upgrade path pins down.
- list_syncable() is the only function that will ever feed a hub, and
  it requires both public and approved. Tests force rows into states
  set_visibility refuses, so the filter is what protects the boundary
  rather than the caller being careful.
- set_visibility refuses anything not approved: media still in the
  moderation queue cannot be marked shared.
- /share lists memes with their current state and asks before making
  one public, since un-sharing stops future copies but cannot recall
  those already taken. The wording describes what sharing will mean
  once a hub exists, because by then warning is too late.
- /list shows the same markers.

Vault posts have no path into the sync set at all; being in a separate
table is what guarantees it, and there is a test saying so.

goyban a35abb0541 Add a vault for saving whole forwarded posts
Completes TODO #5. Forwarding a post now asks whether to save it whole
or extract its media; sending media directly is unchanged.

Built on forwarding rather than copying file_ids. The bot already has
the post in its private chat with the owner, so it stores message ids
and forwards them back. forwardMessages takes a list and keeps an album
intact, which is what made the caption-plus-album case tractable; ids
must be strictly ascending, so they are sorted on the way out.

- Vault rows live in their own table and every query is scoped to an
  owner_id, so a guessed id cannot reach someone else's saved post.
  Nothing in the vault is searchable inline, moderated or federated,
  and the separate table makes that structural rather than a flag.
- Albums arrive as separate messages with no completion signal, so they
  are buffered by media_group_id behind a 1s debounce and prompt once.
- The add path now takes a list of items, so extracting an album stores
  every piece under one set of keywords instead of asking repeatedly.
- /vault searches keywords and the original caption, since the point of
  a vault is finding something you never got round to tagging.
- Retrieval failures are reported: a message id is a pointer into the
  chat, not a self-contained file_id, so clearing history breaks it.

Three near-identical keyword collectors are now one helper.

goyban 82b5da41b8 Add public mode with channel membership requirements
Completes TODO #2. PUBLIC_MODE swaps the ALLOWED_USERS allowlist for a
membership check against REQUIRED_CHATS, with REQUIRE_MODE choosing
between needing every chat or just one.

- Stop is_admin() falling back to "everyone is an admin" when
  ADMIN_USERS is unset once PUBLIC_MODE is on. That fallback is the
  original single-owner convenience, but under public mode it handed
  moderation, /edit and /delete to anyone who found the bot. Public
  mode now grants admin to nobody until ADMIN_USERS is set, and says
  so at startup. Private deployments are unaffected.
- Cache membership answers: inline search queries on every keystroke,
  so an uncached check meant several API calls per typed character.
  Grants last five minutes, refusals thirty seconds, so a user who has
  just joined is not locked out for the full window.
- Fail closed when the membership check errors, and validate
  REQUIRED_CHATS at startup so a chat the bot cannot read is reported
  rather than silently refusing every user.
- Refused users get a join prompt with real links instead of silence;
  inline shows a tappable bar that opens the bot and explains why.
  A private bot stays silent as before.

goyban efc2be5f8a Support audio, documents, stickers and video notes
Completes TODO #6. The bot accepted photo, animation, video, voice and
sticker; music files, documents and round videos were silently dropped.

- Replace the five near-identical media handlers with one dispatch table.
  Animations are matched before documents because Telegram populates
  both fields for a GIF, so the old ordering would have filed every GIF
  as a document once document support existed.
- Store video notes as "video". Telegram has no cached inline result for
  video notes, so this is what keeps round videos searchable; it costs
  the round presentation on playback.
- Build inline results from a table keyed by media_type, and cover audio
  and document. A test asserts every storable type has a builder, so a
  new media type cannot be added without a way to return it.
- Reuse one MEDIA_FILTER for both the idle and mid-keyword handlers;
  the second list had already drifted from the first.
