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.

+// post-bash-stats.mjs — PostToolUse hook (CC v2.1.97+)
+//
+// Captures duration_ms from PostToolUse payload for Bash tool calls and
+// appends a structured stats line to ${CLAUDE_PLUGIN_DATA}/trekexecute-stats.jsonl
+// when the running session is an trekexecute session.
+//
+// Detection: only fires when the tool input matches the verify/checkpoint
+// pattern of an trekexecute step (i.e., the command was issued from inside
+// /trekexecute). We err on the side of "log everything in plugin
+// scope" — duration data is cheap and the alternative is missing real
+// per-step timings.
+//
+// Fail-open invariant: any error → exit 0, no output, no log line.
