Merge main into feat/flowpilot-migration

Brings in PR #141 (PSA ticket management) so FlowPilot can ship on top
of a unified main. Two manual conflict resolutions:

1. CLAUDE.md — kept the FlowPilot ai-handoff rewrite (`.ai/`-driven
   protocol). The pre-rewrite reference content (CW integration notes,
   lessons archive, env vars table) lives in `docs/connectwise/`,
   `docs/LESSONS-ARCHIVE.md`, and DEV-ENV.md by design.

2. frontend/src/pages/AssistantChatPage.tsx — both conflict regions
   were purely additive. Concatenated FlowPilot's Phase 2-9 state hooks
   (facts, activeFix, preview*, scriptPanelOpen, templatizeQueue) with
   PSA's spin-off ticket state (linkedTicket, showNewTicket, spinOffHint).
   Both modal mounts (TemplatizePrompt, ShortcutsHelpOverlay,
   NewTicketModal) kept. All setters wired by either branch are intact.

Verification:
- `tsc -b` clean across the merged tree.
- Browser smoke-test (Session B fixture): Phase 9 ProposalBanner
  ("Run AI-drafted PowerShell to recover SSL VPN") renders alongside
  PSA's new Tickets sidebar icon. Console clean.
