Tom Boucher 315d94f6d4 feat(#1945): tracer-first planning default + executor feedback gate (#2294)
* feat(#1945): tracer-first planning default + executor feedback gate

Make "thin end-to-end slice first, verify, then expand" the default planning + execution discipline instead of the opt-in --mvp mode.

- gsd-planner: first-class `type="tracer"` task; every plan LEADS with one production-quality end-to-end tracer slice by default; --no-tracer restores horizontal layers; --mvp/--tdd compose on top.
- gsd-executor + execute-plan: post-tracer feedback gate — autonomous runs halt-on-fail before expansion, interactive runs emit checkpoint:human-verify after the tracer.
- --no-tracer flag wired through plan-phase workflow/command/help/skill.
- CONTEXT.md glossary defines tracer bullet vs prototype; docs + references reconciled.
- tests/tracer-bullet.test.cjs: prose-contract + behavioral (verify plan-structure accepts tracer) coverage.

Changed 2294

Phase plans now lead with a verified end-to-end "tracer" slice by default — every plan starts with one thin, production-quality slice wired through every layer, which the executor verifies before building out the remaining tasks, so an architectural dead-end surfaces after one commit instead of after ten. Pass --no-tracer to restore the previous horizontal-layer default; --mvp now layers user-story framing and the Walking Skeleton on top of the tracer-first ordering. (#1945)
