feat(pilot): Phase 5 — inline Script Generator integration

Wires the SuggestedFix card to an inline panel that handles both cases:
template-matched fixes open the Script Library generator with parameters
pre-filled from session context; un-matched fixes open the three-option
dialog (one_off / draft_template / build_template). The decision endpoint
records the path choice with side effects: draft_template persists a
draft_templates row via a Sonnet-driven TemplateExtractionService;
build_template returns a redirect to the Script Builder; one_off just
records the choice.

Backend:
- TemplateExtractionService: drafts a parameter schema from a concrete
  rendered script. Conservative by default ("prefer fewer parameters").
  Round-trip-validates that templated_body only references declared
  parameters; missing-key mismatch falls back to the original script
  with no params. LLM/parse failures fall back identically — the
  engineer can still create a draft and refine in the post-resolve
  prompt (Phase 6).
- /suggested-fixes/{fix_id}/decision side effects:
  * one_off → returns rendered_script (engineer's edited version or the
    fix's ai_drafted_script verbatim)
  * draft_template → same + creates draft_templates row with extracted
    params, returns draft_template_id
  * build_template → returns redirect_path=/scripts/builder?from_session=
    &fix= so the frontend can navigate to the builder pre-loaded
- 400 when a non-template fix has no ai_drafted_script (template-matched
  fixes take the dedicated /scripts/generate path, not this endpoint).
- 12 tests: TemplateExtractionService parse + fallback paths, all four
  decision branches, edited_script override, missing-script 400.

Frontend:
- src/components/pilot/script/{TemplateMatchPanel, NoTemplateDialog,
  ParameterizationPreview}.tsx — inline panels rendered in the task
  lane's bottom slot when the engineer clicks a SuggestedFix card.
- TemplateMatchPanel: loads template via /scripts/templates/{id},
  pre-fills params from fix.ai_drafted_parameters with cyan "from
  session" tags, generates via existing /scripts/generate (already
  bumps state_version on ai_session_id from Phase 3). 404 falls back
  with a clear message instead of erroring.
- NoTemplateDialog: shows the AI-drafted script with proposed parameter
  values highlighted in amber via ParameterizationPreview; three option
  cards with the middle (draft_template) flagged Recommended; inline
  edit on the script body before deciding.
- SuggestedFix card now clickable: onActivate toggles the inline panel.
- AssistantChatPage: scriptPanelOpen state + handleScriptDecision that
  navigates on build_template and toasts on the other paths. Active fix
  changes auto-close the panel so engineers don't act on stale state.
- Cmd+K → "Open inline Script Generator" palette entry surfaces only on
  /pilot/:id routes; fires a window event the chat page subscribes to.
  No Resolve shortcut added per Section 14 decision (browser ⌘R conflict).

Verified 2026-04-22 against the dev stack:
- one_off / draft_template / build_template all return the right shape
  with real Sonnet TemplateExtractionService for the draft path.
- Conservative extraction confirmed: cmdkey + Restart-Process script
  yielded zero proposed parameters as intended.
