docs(changelog): move 0.9.5 features from [Unreleased] into [0.9.5]

The 0.9.5 release tag included all of:
- Shared MCP daemon (#411)
- Per-file staleness banner (#403)
- Worktree-borrow detection (#312)
- Watcher inotify-budget fix (#276)
- Objective-C indexing (#165)
- Mixed iOS / React Native / Expo cross-language bridging (#430)

But the [0.9.5] block in CHANGELOG.md only had two Fixed entries (the
fs-based change detection and default-ignore set), because the major
feature entries were still sitting under [Unreleased] when 0.9.5 was
tagged. release.yml extracts release notes from the matching version
block, so the published v0.9.5 release notes are missing the bulk of
what shipped.

Move all the [Unreleased] entries that pre-date 0.9.5's tag (commit
318cda1) into [0.9.5], and reset [Unreleased] to empty. The GitHub
Release notes for v0.9.5 get updated separately via gh release edit.
