Subject: [PATCH] fix(release): filter release changelogs to lane-specific
 paths

Release PR changelogs were listing every commit in the monorepo since
the last lane tag. `format_log` ran `git log <range>` with no path
filter, so e.g. `relay-v0.1.1..HEAD` captured 327 commits across
desktop, mobile, and all crates rather than the ~35 touching relay code.

Adds a `LOG_PATHS` array to each lane's `case` block and passes it as
a `-- <paths>` filter to `git log` in `format_log`. Each lane's scope:
- relay: buzz-relay + its compiled deps (buzz-core, buzz-db, buzz-auth,
  buzz-pubsub, buzz-search, buzz-audit, buzz-media, buzz-sdk,
  buzz-workflow, buzz-conformance) + migrations/
- desktop: desktop/ + its Rust deps (buzz-core, buzz-persona, buzz-sdk,
  buzz-agent)
- mobile: mobile/ only (no Rust crate deps)
