Backfill 0.2.106 release notes

[TheGreatAxios]

The [0.2.106] section covered only the first four merges after the v0.2.105 tag. Roughly fourteen PRs merged since then without changelog entries, and [Unreleased] was empty — so tagging now would have shipped a release whose notes omitted most of its contents.

This backfills the user-visible ones, grouped under the existing Agent / Interface / Safety headings:

Agent — apply_patch Update fixed (CL-6966) · sticky hard-block false positives removed (CL-6964/6704/6710) · read_file continuation handle (CL-6961) · edits return a bounded diff (CL-6962) · Responses adapter reasoning/dedupe/codec fixes (CL-6912) · byte-stable compacted prefixes (CL-6914) · per-model repetition visibility (CL-6775)

Interface — context meter resets and re-syncs (CL-6933) · compaction is visible (CL-6934) · no false "awaiting response" during fan-out (CL-5661)

Safety — OAuth scope verified before onboarding completes (CL-5710) · approval ask/settle log (CL-5666)

Deliberately omitted as internal, with no user-visible behavior: test files brought into typecheck scope (CL-5759), TUI test renderer leak (CL-5539), stop-policy comment scrub (CL-6789), repetition detector consolidation, the eval suite reset (#577), release-script PR routing (CL-6957), and the segment-naming diagnostic (CL-6960).

No known-issues section, per the release rules.
