chore(release): 0.9.0

[pbean]

Release prep for 0.9.0 (minor). Bumps the version everywhere, regenerates the TUI screenshots + demo, and finalizes the CHANGELOG. The vX.Y.Z tag + GitHub release are created automatically by the Release workflow when this merges to main.

What this commit does

• Stamps 0.9.0 across pyproject.toml, src/bmad_loop/__init__.py, module.yaml, the setup-asset module.yaml, .claude-plugin/marketplace.json, and regenerates uv.lock.
• Regenerates docs/images/ (7 screenshots + demo.gif) — src/bmad_loop/tui changed since v0.8.1.
• Promotes the curated [Unreleased] CHANGELOG section to ## [0.9.0] — 2026-07-21 and inserts the release link ref.
• Adds one missing CHANGELOG entry found while auditing commits since v0.8.1: the worktree-seed-skipped journal event (A worktree_seed directory entry is skipped entirely when any child is tracked #230, PR fix: report worktree_seed entries skipped as no-ops #233). Everything else since v0.8.1 was already documented.

Release highlights (0.9.0)

A large minor release. Added: OpenCode opencode-http adapter, native-Windows psmux multiplexer backend (experimental, #58), out-of-tree mux backends via entry points, stories-mode planning pipeline + per-story checkpoints, graceful stop (stop --graceful / TUI S), active-agent indicator (#153), mid-session token-budget guard (#158), resizable TUI panes, dev-choosable mux backend selection (#87), Unity modal-dialog guards, follow-up-review damping, and five machine-readable --json surfaces (status/list/decisions/clean/cleanup/validate). Plus a broad slate of resume/teardown/verify hardening fixes. See CHANGELOG.md for the full list.

Verification

• python scripts/release.py check → version-sync agrees on 0.9.0; CHANGELOG section present.
• trunk check --no-progress → clean (22 modified files).

Poem

A bunny stamped the version bright,
From eight-one to nine-oh light.
The changelog hops into the sun,
And logs skipped seeds, one by one.
Release carrots neatly aligned—
0.9.0, wonderfully signed!
