Drops all GitHub-specific tooling (gh CLI, draft PR creation) so the
workflow stops at git commit and leaves push/PR/MR to the user.
TODO.md is now expected to be a tracked file on the default branch.
Phase 1 verifies the repo is bare via `git rev-parse --is-bare-repository`,
resolves the default branch from HEAD / init.defaultBranch, and snapshots
TODO.md via `git show "$DEFAULT_BRANCH:TODO.md"` to a tempfile that @pm
reads in Phase 2. Phase 10 updates the live TODO.md inside the worktree
and commits the change separately. The /review command drops its PR
mode for the same reason; @pm documents the read-only-snapshot vs.
live-worktree path distinction.
Adds @check, @simplify, @test, @make, @pm subagents and the /workflow
and /review slash commands from the autonomous multi-agent workflow
gist by ppries.
@pm is rewritten to manage issues in a local ./TODO.md file instead of
Linear (file-only access, documented schema, structured JSON output).
/workflow is adapted: TODO.md-based issue context, generic worktree
paths (no hardcoded ~/repos/veo/sunstone), generic branch examples,
and a Phase 1 guard that verifies origin is on GitHub before any
work begins.
