fix(cli-registry): merge-time fixes for the run-menu consolidation (#458)

- test/opencode-resize.test.ts: retarget the launcher guard at the real code (this.selectSession(firstSessionId), any this.activeSessionId assignment) with an anti-vacuity check; the old strings existed nowhere, so it could never fail
- session-ui.js: restore as comments the two invariants the merged bodies lost (deepseek leaves statusReporting unset, i.e. ON; no effort field for external CLIs, it is Claude-specific)
- docs/cli-registry.md: move the frontend-guard paragraph below the two backend-guard paragraphs so they keep their antecedent, and note the widened comparison shape
- test/frontend-cli-no-id-branching.test.ts: the comparison shape accepts any left-hand identifier (const m = this._runMode; m === 'codex' was invisible), normalized to `mode`; the two `m !== 'shell'` display filters are allowlisted and the remaining blind spots documented
- test/run-mode-dispatch.test.ts: table-driven pin of run() dispatch (claude to runClaude, each RUN_MODE_LAUNCH id to _runCliMode(id), shell to runShell, unknown to runClaude, lock held and released)
- CLAUDE.md: name the second CI-gated guard next to the backend one
- server.ts: every </head> injection passes a replacer function; a clis.json label containing $' re-injected the rest of the document past escapeScriptJson (two render tests pin it, proven failing on the string form)
- _isAltCliMode(): no reference anywhere in the tree, nothing to fix
