constellation:
- restore getBacklinkDids XRPC endpoint (it exists in source)
- add getManyToMany endpoint (list items, not just counts)
- fix limits back to 100/1000 (source constants, web docs were stale)
- confirm cursor support on all paginated endpoints
- document /links/all endpoint for exploring all link types

slingshot:
- add blue.microcosm.identity.resolveMiniDoc (new stable path)
- add blue.microcosm.repo.getRecordByUri (ergonomic AT-URI endpoint)
- note com.atproto.sync.getRecord is work in progress
- note listRecords is not supported
- migrate examples from com.bad-example to blue.microcosm namespace

spacedust:
- add filter limits (subjects 50k, DIDs 10k, prefixes 100, sources 1k)
- document AND/OR semantics: subject filters OR each other, AND with sources

app-patterns:
- migrate to blue.microcosm namespace in examples

- getManyToManyCounts is for many-to-many relationships, not batch queries
- getBacklinkDids XRPC endpoint doesn't exist (legacy /links/distinct-dids only)
- default limit is 16, max is 100 (not 100/1000)
- update app-patterns to use parallel getBacklinksCount instead of wrong batch endpoint
