feat(voyage)!: marketplace handoff — rename plugins/ultraplan-local to plugins/voyage [skip-docs]

Session 5 of voyage-rebrand (V6). Operator-authorized cross-plugin scope.

- git mv plugins/ultraplan-local plugins/voyage (rename detected, history preserved)
- .claude-plugin/marketplace.json: voyage entry replaces ultraplan-local
- CLAUDE.md: voyage row in plugin list, voyage in design-system consumer list
- README.md: bulk rename ultra*-local commands -> trek* commands; ultraplan-local refs -> voyage; type discriminators (type: trekbrief/trekreview); session-title pattern (voyage:<command>:<slug>); v4.0.0 release-note paragraph
- plugins/voyage/.claude-plugin/plugin.json: homepage/repository URLs point to monorepo voyage path
- plugins/voyage/verify.sh: drop URL whitelist exception (no longer needed)

Closes voyage-rebrand. bash plugins/voyage/verify.sh PASS 7/7. npm test 361/361.

+# CLI parser conventions in small-auth
+
+## Executive Summary
+
+`small-auth` uses a hand-rolled argv parser at `src/cli.mjs:12-58` with a
+two-pass approach: first pass extracts global flags (currently
+`--help`, `--version`), second pass dispatches to command handlers in
+`src/commands/*.mjs`. Adding `--verbose` requires touching only the
+first-pass extractor and a new `verbose` parameter in the handler
+contract — six command handlers each get a one-line update.
+
+The parser does **not** use `commander`, `yargs`, or any external
+library — this is intentional (zero deps) and consistent with the
+plugin marketplace's broader convention. We keep that.
+
+`stderr` is currently unused except for fatal errors. Adding verbose
+output to stderr does not collide with anything.
+
+Confidence: 0.85. The 0.15 uncertainty is around whether
+`--verbose` should propagate into nested helper modules
+(`src/lib/auth-token.mjs` calls `src/lib/db.mjs`); the plan should
+either pass `verbose` via a context object or use a module-scoped
+log function. Both work; the brief doesn't specify, so the planner
+will choose.
+
+## Dimensions
+
+### 1. Argument-parsing layer
+
+The parser at `src/cli.mjs:12-58` returns
+`{globalFlags: {help, version}, command, positional, commandFlags}`.
+We add `verbose: boolean` to `globalFlags`. The two-pass design means
+`--verbose` works in any position automatically — no extra effort.
+
+`-v` short form maps to `--verbose` via the existing alias table at
+`src/cli.mjs:34`.
+
+### 2. Command-handler contract
+
+Each handler in `src/commands/*.mjs` exports
+`async function run(positional, flags, ctx)`. Today `ctx` is
+`{stdout, stderr, env}`. We extend `ctx` with `verbose: boolean` so
+handlers can branch on it without re-reading globalFlags.
+
+### 3. Internal log emission pattern
+
+Existing fatal errors call `ctx.stderr.write(\`[error] ...\\n\`)`. The
+verbose pattern matches: `if (ctx.verbose) ctx.stderr.write(\`[verbose] ...\\n\`)`.
+No log helper needed for this iteration — six call sites total. Refactoring
+into a `verbose()` helper is reasonable but not required for the goal.
+
+### 4. Test infrastructure
+
+Tests live in `tests/*.test.mjs` using `node:test`. Existing tests run
+the CLI as a subprocess via `child_process.execFile` and assert on
+exit code + stdout. Two new tests are needed:
+
+- `tests/cli-verbose-flag.test.mjs` — assert `login --verbose alice`
+  exits 0, stderr contains "[verbose]", stdout matches golden file.
+- `tests/cli-no-verbose-stability.test.mjs` — assert
+  `login alice` stdout is byte-identical to `tests/golden/login.stdout`.

+
+## Brief anchoring
+
+Brief task: "Add a --verbose flag to the small-auth CLI parser".
+This research answers the planner's first question: where to hook
+into. The parser is small and centralized, so the change is
+minimal-scope.
+
+The brief's success criteria around byte-identical default stdout
+maps directly to the stability test in dimension 4.
