Add inline review comments to git diff pane (#530)

* Add inline git diff review comments

Adds a review draft store keyed per diff target, inline gutter + thread
rendering in the diff pane, and a generated review attachment that flows
through the composer and agent providers.

* Strip generated review attachments before saving to draft store

Drafts persist only UserComposerAttachment (no review kind), so filter the
auto-generated review attachment out when seeding the draft or restoring
after a failed auto-submit.

* Fix inline review typecheck and test harness drift

* Unslop inline review feature

- Fix stale-closure bug in composer queueMessage: clear drafts for the
  actually-queued attachments, not the latest props
- Drop dead useEffect mirroring initialBody in inline review editor
  (parent already remounts via key)
- Restore typed AgentAttachment signature on renderPromptAttachmentAsText;
  delete schema redispatch helper and drop null-checks across 5 providers
- Inline single-use review prompt formatters and replace marker switch
  with const map
- Drop normalizeComment field-copy redundancy after type guard
- Remove __reviewDraftStoreTestUtils export; test migration via
  rehydrate() public path
- Refactor findTarget to return the target line directly (no non-null
  assertion at call site)
- Drop redundant isGeneratedReviewAttachment helper; inline kind check

* Update review pill to withUnistyles after rebase

Main's unistyles refactor stripped useUnistyles in favor of withUnistyles +
StyleSheet. Convert ReviewAttachmentPill to use ThemedCircleDot + ICON_SIZE so
the icon picks up the foreground-muted mapping like the other pills.

* Fix lint and typecheck after rebase onto main

Resolve drift after main's withUnistyles refactor:
- Composer complexity: dedup voice?.isVoiceSwitching to drop to 20
- Move per-comment Pressable handlers in git-diff-inline-review into
  CommentRow subcomponent so callbacks are stable
- Hoist style/onPress factories to module level (iconButton,
  iconButtonDestructive, ghostButton)
- Memoize style arrays in git-diff-pane review wrappers
- Replace inline {} placeholders with useMemo styles
- review-draft-store: extract applyCommentUpdates to avoid map-spread,
  include input.key in useMemo deps
- Test fixtures: hoist EMPTY_COMMENTS, add buildReviewActions helper

* Drop GitDiffPane default param to keep complexity at 20

After the rebase, main's `enabled = true` default param combined with the
inline review additions pushed cyclomatic complexity to 21. Drop the
default and resolve `enabled !== false` at the call site (comparison
doesn't count toward complexity).

* Reshape inline review behind @/review module

Drop the `generated: true` attachment flag and consolidate inline-review
logic behind a deep `@/review` module so composer and git-diff-pane stop
hand-composing review primitives. Workspace-scoped review snapshots are
now derived at submit/queue time rather than persisted in the draft
store. Composer review references drop from 51 to 4; git-diff-pane drops
~108 lines and now consumes a controller hook + slot components.

* Fix optimistic review attachments
