docs(01-01): complete doc-cascade plan

Plan 01-01 (Wave-0 doc cascade) complete. Six tasks landed atomically
in commits 125c032, fb88830, b1ed2cb, 597d967, 32bc996, 4a5194e. Every
code-touching plan in Phase 1 (01-02..01-07) now reads a consistent
baseline: getDisplayMedia replaces tabCapture in DEC-003; long-lived
port replaces alarms in DEC-010; manifest.json carries the final
Phase-1 permissions set (desktopCapture, activeTab, downloads,
scripting, storage, offscreen).

+- [Phase ?]: Doc cascade: amendments append (do not replace) original DEC/CON blocks to preserve SPEC provenance — Established convention for future SPEC-amending phases; downstream readers see both old + new with citation
+- [Phase ?]: Manifest: drop alarms permission entirely rather than retain for re-use — Plan 05 deletes the alarms code path; declaring unused permissions expands attack surface (T-1-02)
