b4bfe083be MUL-6407: mint UUIDv7 primary keys for append-heavy tables (#7230)
* perf(db): mint UUIDv7 primary keys for the append-heavy tables

Random v4 primary keys scatter every insert across the whole primary-key
B-tree, so each row dirties a different page. On the tables that grow
continuously — the task queue, messages, comments, activity and audit rows —
that is pure write amplification. UUIDv7 puts a big-endian millisecond
timestamp in the leading 48 bits, so consecutive inserts share a page.

The 12 tables converted here are the append-only hot paths:

  agent_task_queue, activity_log, inbox_item, comment, issue, chat_session,
  chat_message, autopilot_run, webhook_delivery, task_token,
  channel_inbound_audit, sys_cron_executions

Ids come from the new pkg/dbid, which returns a pgtype.UUID ready to assign to
a sqlc params struct. Upsert-dominated tables (task_usage, agent_runtime, ...)
are deliberately left alone: v7 only buys locality for rows that are actually
inserted. Lease and claim tokens keep gen_random_uuid() — they must stay
unpredictable and carry no timestamp.

No migration, and no backfill. Every converted INSERT binds its id as
COALESCE(sqlc.narg('id')::uuid, gen_random_uuid()), so the column default stays
reachable: a caller that passes no id inserts exactly as it does today. Tables
will hold a mix of v4 and v7 ids permanently, which the uuid type and every
parser in the repo already accept.

Verification: - pkg/dbid: version/variant, uniqueness, and a non-decreasing timestamp
    prefix; a shape test asserting every converted query keeps the COALESCE
    fallback; and a source scan asserting every production params literal mints
    an id, so a call site added later cannot silently fall back to v4.
  - internal/handler: round-trips issue, comment, activity_log, inbox_item,
    chat_session, chat_message, agent_task_queue, task_token and
    channel_inbound_audit against Postgres and asserts the stored id is v7,
    plus one case proving an unset id still inserts (as v4).
  - internal/scheduler: covers the one hand-written INSERT, asserting the
    execution id is v7 while lease_token stays v4.

// and the :one query returns pgx.ErrNoRows. A wrong workspace can therefore
// never leave a mis-attributed comment or a silently un-touched issue.
//
// Centralizing this here means every comment entrypoint inherits both
// guarantees regardless of what a caller passes. The "Updated date" sort and
// the daemon GC TTL both read updated_at, so this consistency is load-bearing.

// path instead of generic comment/mention routing.
// Planned ids matter for retry children because their input comments predate

// replays the remainder through the normal trigger pipeline oldest first.
//
// Author-type scope (MUL-4304): originally restricted to author_type = 'member'.

// it then keeps ONLY explicit @agent/@squad mention triggers

// other conversational routing are dropped, so a plain agent reply /
// acknowledgement yields nothing regardless of issue assignment. The reconcile
// pass further keeps only triggers routing to the agent that just completed, so
