[P1] Mark changes feed sequence numbers as int64
seq is backed by db.SequenceID (uint64 for the simple form), and leaving the integer branch unformatted means many OpenAPI generators default this to int32, which can overflow/truncate real-world sequence values. Add format: int64 to the integer variant so generated clients treat sequence numbers as 64-bit.

Pull request overview
This PR updates Sync Gateway’s OpenAPI documentation to match the actual server behavior and constants around _changes, _dumpchannel, and view query parameters.
Changes:
- Corrects the
_changeschannel filter documentation to usesync_gateway/bychannel(matchingbase.ByChannelFilter). - Documents that
Changes-feed.results[].seqcan be either an integer or a compound string sequence value (matchingdb.SequenceID.MarshalJSONbehavior). - Fixes admin
_dumpchannel?sinceto be a plain integer sequence number (matchingrest/handler.getIntQueryusage) and expandsstaleenum support to include"false".

- `javascript_timeout_secs` documented a default of 60, but
`base.DefaultJavascriptTimeoutSecs` is 0 (uncapped).
- `revs_limit` documented `minimum: 0`, which config validation rejects
("must be greater than zero"). Use 1, and note the higher floor and
different default that apply when `allow_conflicts` is enabled.
- The stats logger's `max_age` documented a default of 6. Unlike the other
loggers it does not derive its default from `minAge`; it uses the fixed
`statsDefaultMaxAgeOverride` of 90. The error/warn/info/debug/trace and
audit defaults were checked and are correct.

max_processes is a uint, and db/event_manager.go:69-70 maps 0 to kMaxActiveEvents (500), so document minimum: 0 with the effective default and say what 0 means. Raised by Copilot on #8654. heartbeat and timeout in the _changes POST bodies now carry the same defaults and bounds already documented on the GET query parameters: heartbeat defaults to 0 and, when non-zero, is clamped up to kMinHeartbeatMS (25000); timeout defaults to kDefaultTimeoutMS (300000) and is capped at kMaxTimeoutMS (900000). See GetRestrictedInt, which readChangesOptionsFromJSON calls with allowZero=true. Copilot flagged these as heartbeat-only, but the timeout default is 300000, not 0. Also drops the revs_limit allow_conflicts note. Both branches it describes exist (db/database.go:504-508, rest/config.go:936-940) but neither is reachable from config: allow_conflicts=true is rejected in the same validateVersion (rest/config.go:1149-1150) and DefaultAllowConflicts is false, so only the test-only EnableAllowConflicts gets there. Raised by @factory-droid on #8656. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- The channel filter is `sync_gateway/bychannel` (`base.ByChannelFilter`), not `sync_gateway/bychannels`. The `filter` enum already had it right; four `channels` descriptions did not. - `Changes-feed.seq` was documented as an integer, but `SequenceID.MarshalJSON` emits a quoted compound string whenever `TriggeredBy` or `LowSeq` is set (e.g. during a channel backfill), so clients must handle both. - `_dumpchannel?since` is read with `getIntQuery`, so it is a plain sequence number, not the opaque `last_seq` value the description described. - `stale` also accepts `false`, which is the value Sync Gateway's own view queries use. - The stats logging block was described as "Trace logging configuration".

Split out of #8589 — stack 9/9, based on #8656.
sync_gateway/bychannel(base.ByChannelFilter,base/constants.go:137), notsync_gateway/bychannels. Thefilterenum already had it right; fourchannelsdescriptions did not. (Raised by @factory-droid on CBG-5715 docs(api): fix OpenAPI errors #8589.)Changes-feed.seqwas documented as an integer, butSequenceID.MarshalJSON(db/sequence_id.go:155) emits a quoted compound string wheneverTriggeredByorLowSeqis set (e.g. during a channel backfill), so clients must handle both._dumpchannel?sinceis read withgetIntQuery(rest/bulk_api.go:359), so it is a plain sequence number, not the opaquelast_seqvalue the description described.stalealso acceptsfalse, which is the value Sync Gateway's own view queries use. Worth a reviewer's eye:rest/view_api.go:100passesstalethrough to the view engine verbatim, so nothing in SG validates the value set — the enum as a whole is unverifiable from the code, and dropping it may be more honest than extending it.Pre-review checklist
