Merge gitea/main into the Motion branch

Motion was written against a base five commits behind main, so the
integration is the interesting part of this commit:

- The migration is renumbered 0014 -> 0015. Main shipped
  0014_piggy_conversations, and two migrations sharing an index is a
  journal that applies one of them.
- The seed-idempotency gate keeps main's all-tables diff rather than the
  motion_templates counter this branch added; the general check subsumes
  the specific one.
- Nav gains a Motion group alongside main's new Workspace group, and
  Piggy keeps the mark main gave it.
- Stat keeps main's container-scaled figure, which already carries the
  min-w-0 this branch added for the same reason.
- Piggy's page labels keep main's refusal wording for the four pages with
  no tool of their own, and gain the three Motion routes.

/**
* What an activity looks like on the wire, and who is recorded as having done it.
*
* Two endpoints render a timeline — the account record and the dashboard feed —
* and both selected the whole row, so the payload was whatever the table
* happened to hold that week. That is how `meta` came to ship every stage
* transition blob and Slack permalink to every browser, and it is why nothing
* on the client could safely depend on `external_id` being there at all: it
* arrived by accident, and the next hand-written column list would have removed
* it without anyone noticing. The projection is declared here instead, once,
* and shaped around the two questions a reader of a timeline actually asks:
* what happened, and who did it.
*
* **Who did it is the part that was broken.** Piggy signs a row in one of two
* places, because it makes two shapes of write:
*
* - `pig_log_activity`'s row IS its own audit event, so there is no separate
* audit row to stamp. It carries an `external_id` of `piggy:<uuid>`, which
* doubles as the idempotency key that stops a retried tool call logging the
* same conversation twice (`write-tools.ts`).
* - Every other write tool leaves `meta.actorAgent = 'piggy'` on the audit row
* the mutation convention inserts beside the change (`attributedToPiggy`).
*
* `activities.actor_agent` itself stays exactly what it has always been — set
* only when the request authenticated as an agent — because a browser session
* authorised by a person really was authorised by that person, and stamping it
* otherwise would be a lie told inside the audit trail. So the derivation lives
* on the read, not on the row: the wire says "an agent produced this entry, and
* it was Piggy", which is precisely what the column means, while the stored row
* goes on recording how the request was authorised. Nothing here writes.

*
* The policy, stated once, because two files were quietly contradicting each
* other about it:
*
* **Cost and outcome are the company's record. The words are the person's.**
*
* `piggy-conversations.ts` already says so at the top and enforces it with a
* predicate that a platform admin is no exception to. `PiggyActivityService`
* says the same thing in its header — and then returned `label`, which is the
* user's question cut to 180 characters, and `summary`, which is the first line
* of Piggy's answer, for every run in the workspace once the caller was an
* admin. So the ledger was a keyhole into exactly the material the transcript
* store refuses to hand over, and while `piggy_messages` was never written it
* was the ONLY copy of a conversation anyone could reach.
*
* Now that transcripts persist properly the contradiction has no excuse left,
* and it is settled the way the conversation store settles it. An admin keeps
* everything they need — what ran, whose it was, whether it failed, what it
* cost, how long it took — and loses the two fields that are somebody's private
* questions about the book. An admin reading their OWN runs sees them in full,
* as does everybody else, because `runs` scoped to a caller returns no
* `principal` on their own rows: that field is populated only when the run
* belongs to somebody else, which makes it the exact signal this needs.
*
* It sits in the route rather than the service on the reasoning this file
* opened with — the service computes the ledger, the route is the gate — and
* because `overview` has one caller. Should a second appear, this moves down.
*
* One case is deliberately left open, and is written down rather than left to
* be discovered. `agent_runs.principal_user_id` is `ON DELETE set null`, so a
* departed colleague's runs survive with no owner, and the service reports an
* ownerless run exactly as it reports the caller's own: `principal: null`. To
* an administrator those two are indistinguishable from here, so a leaver's
* questions stay legible while a current colleague's do not. Closing it needs
* `PiggyRunSummary` to say whose a run is not, rather than only when it is
* somebody else's — a change in the service, and the wrong thing to guess at
* from the gate. The retention question underneath it is larger still: the
* ledger keeps `input.message` after the transcript it belonged to has been
* cascaded away with its author.

* anything here. In short: a turn gets `SessionManager.inMemory()` and the
* history is rehydrated from Postgres, because a file under the agent
* directory is neither per-user nor able to survive a second replica.
*
* Two rules hold everywhere in this file.
*
* **Ownership is a predicate, never a check after the fact.** Every statement
* carries `user_id = $me`, so another person's conversation and a UUID that
* does not exist are the same answer: nothing. Reading a row and then
* comparing its owner would work equally well until the day someone adds a
* path that forgets the comparison, and that path would return the row.
*
* **A platform admin is not an exception.** Everywhere else in PIG being an
* administrator widens what you can see, and here it must not: a transcript is
* a person's own half-formed questions about the book, and nobody asked to
* have it read. Cost and audit live in `agent_runs` and `activities`, which is
* where an administrator looks.
*
* Writes here do NOT go through `executeMutation`, which is otherwise the
* chokepoint for every write in the API. That convention exists to enforce
* capabilities and to write an audit activity, and both reasons are absent: a
* conversation is scoped to its owner rather than to a team, and an activity
* row per message would put "Started a Piggy conversation" into the account
* feed and the dashboard's recent activity dozens of times a day, drowning the
* log the convention exists to keep readable. The writes Piggy performs ON THE
* CRM still go through `executeMutation`, as the calling user — that is a
* different code path (`apps/piggy`), and it is the one that must stay honest.

* evidence sorts above the question it answered is not a transcript. One
* promise chain, appended to, keeps the order the stream had.

* be able to reach the stream the user is reading. None of that needs SQL, and

/**
* That a Piggy transcript belongs to exactly one person.

* The failure this suite exists to prevent is not exotic. Every statement in
* `PiggyConversationService` carries `user_id = $me`; the day one of them does
* not, the route above it keeps working perfectly for its author and quietly
* starts answering for everybody else's history too, with no error anywhere.
* So the assertions are made twice, at two different depths:
*
* - against a recording driver, which runs in the default suite and pins
* that the predicate actually reaches SQL on every path, including the
* ones a fake row store would happily let through;
* - against a real Postgres, which is where a cascade, a unique key and a
* CHECK constraint are either true or not. That half needs a database and
* therefore names its own:
*
* createdb pig_piggy_test
* DATABASE_URL=postgres://…/pig_piggy_test pnpm -F @pig/db run migrate
* PIG_TEST_DATABASE_URL=postgres://…/pig_piggy_test \
* pnpm -F @pig/api run test
*
* A deliberately separate variable from `DATABASE_URL`: this suite writes
* and deletes rows, and it must be impossible to point it at a working
* database by inheriting the environment.
