chore(voyage): release v5.0.1 — drop standalone HTML render; print literal /playground document-critique invocation

The v5.0.0 stop-gap had /trekbrief, /trekplan, and /trekreview each render
a read-only {artifact}.html (via scripts/render-artifact.mjs) AND print a
vague "run the /playground plugin" instruction. In practice the read-only
HTML was redundant with what /playground produces and the instruction
wasn't copy-paste-ready — the operator had to guess the right invocation.

v5.0.1 deletes scripts/render-artifact.mjs + its test + npm run render,
and makes each producing command end with a single boxed, literal,
copy-paste-ready line:

    /playground build a document-critique playground for {artifact_path}

One paste from the operator launches the official playground skill's
document-critique template, which builds an interactive HTML — artifact
on the left, per-line Approve/Reject/Comment cards on the right, Copy
Prompt button at the bottom. Mark suggestions, click Copy Prompt, paste
back, Claude revises the .md. Doc-consistency test pins the literal
invocation so the prose cannot soften back into vagueness.

npm test green: 503 tests, 501 pass, 0 fail, 2 skipped.

 Deep requirements gathering, research, implementation planning, self-verifying execution, independent post-hoc review, and zero-friction multi-session resumption — with specialized agent swarms, adversarial review, and failure recovery. Six-command (brief, research, plan, execute, review, continue) universal pipeline. `/trekbrief`, `/trekplan`, and `/trekreview` render their artifact to a self-contained HTML view and print the `file://` link; annotation is delegated to the official `/playground` plugin.
 
-v5.0.0 (breaking) **removes the bespoke playground.** v4.2/v4.3 shipped a ~388 KB bespoke playground SPA + `/trekrevise` + Handover 8 (annotation → revision); a browser walkthrough found it borderline unusable and it duplicated the official `/playground` plugin's `document-critique` / `diff-review` templates. The SPA, the `/trekrevise` command, Handover 8, the supporting `lib/` modules (`anchor-parser`, `annotation-digest`, `markdown-write`, `revision-guard`), the Playwright e2e suite, and the `@playwright/test` / `@axe-core/playwright` devDeps are all deleted. In their place: a small, zero-dependency `scripts/render-artifact.mjs` that renders any brief/plan/review `.md` to a self-contained, design-system-styled, zero-network `.html` (frontmatter folded into a `<details>` block). The producing commands call it on their last step and print the link; to annotate, run `/playground` (`document-critique`) on the `.md` and paste the generated prompt back — Claude revises the artifact freehand. Forks depending on the removed surfaces migrate to the `/playground` plugin. See `plugins/voyage/CHANGELOG.md` § v5.0.0.
+v5.0.1 finishes the annotation-UX work that v5.0.0 started: at the end of `/trekbrief`, `/trekplan`, and `/trekreview` the operator now gets a single boxed, copy-paste-ready line — `/playground build a document-critique playground for {artifact_path}` — that launches the official `claude-plugins-official` `playground` skill's `document-critique` template. One paste builds a self-contained HTML with the artifact on the left, per-line Approve/Reject/Comment cards on the right, and a Copy Prompt button at the bottom; copy the generated prompt, paste back, Claude revises the `.md` freehand. v5.0.1 also dropped the v5.0.0 stop-gap `scripts/render-artifact.mjs` (a separate read-only HTML render) and the `npm run render` alias — they were redundant with what `/playground` produces. v5.0.0 (breaking, kept) removed the v4.2/v4.3 bespoke playground SPA, `/trekrevise`, Handover 8, the supporting `lib/` modules (`anchor-parser`, `annotation-digest`, `markdown-write`, `revision-guard`), the Playwright e2e suite, and the `@playwright/test` / `@axe-core/playwright` devDeps — a browser walkthrough had found the bespoke surface borderline unusable, and it duplicated the official `/playground` plugin. Forks depending on the removed surfaces migrate to `/playground`. See `plugins/voyage/CHANGELOG.md` § v5.0.0 + § v5.0.1.
 
 v4.0.0 (breaking) renamed the plugin from `ultraplan-local` to **Voyage** and all commands from `/ultra*-local` to `/trek*` to remove name collision with Anthropic's `/ultraplan` and `/ultrareview` features. See `plugins/voyage/TRADEMARKS.md` and `plugins/voyage/CHANGELOG.md`.

 - **`/trekreview`** — Close the iteration loop. Independent post-hoc reviewer reads `brief.md` from scratch and evaluates the diff produced by execute. Two parallel reviewers (brief-conformance + code-correctness) plus a Judge Agent (review-coordinator) for dedup and reasonableness filtering. Severity-tagged findings (Critical/High/Medium/Low/Info) with stable 40-char hex IDs feed back into planning via Handover 6 (`/trekplan --brief review.md` → remediation plan with `source_findings:` audit trail).
 - **`/trekcontinue`** — Zero-friction multi-session resumption. In a fresh chat, type `/trekcontinue` — reads `.session-state.local.json` (Handover 7), prints a 3-line summary, and immediately begins executing the next session. Any session-end mechanism may write the state file (`/trekexecute` Phase 8/2.55/4 do so automatically; `/trekendsession` helper writes it for informal flows). Forward-compat schema (unknown top-level keys ignored) so future producers can extend additively.

 v3.4.0 (non-breaking) adds the **autonomy chain from brief approval to main-merge** plus parallel-wave hardenings. New `lib/util/autonomy-gate.mjs` state machine (`idle → approved → executing → merge-pending → main-merged`), `lib/review/plan-review-dedup.mjs` for Phase 9 inline dedup, `lib/stats/event-emit.mjs` for autonomy-gate transitions and main-merge gate, and `--gates {open|closed|adaptive}` flag on all four pipeline commands. `commands/trekplan.md` Phase 8 seals Opus-4.7 plan/list-emission schema-drift via `plan-validator --strict`. `commands/trekexecute.md` Phase 2.6 wave-executor adds 11 hardenings for plugin-in-monorepo + gitignored-state topology (GIT_OPTIONAL_LOCKS, --max-turns, --max-budget-usd, scoped --allowedTools, push-before-cleanup ordering). New `hooks/scripts/post-compact-flush.mjs` PostCompact hook re-injects session-state after compaction. SC7 synthetic determinism floor (Jaccard ≥ 0.833) for plan + review fixtures. Hook baseline regression pins. Architecture decision: Path B (sequential `--no-ff` parallel waves with manifest-driven failure recovery) ships; Path C (cache-first hybrid) deferred to v3.5.0 contingent on cache-telemetry harvest.
