Ben Stull 4afb018bb0 Contribute rewrite Phase 5: inline word-diff in manual pending card
The §8.11 manual-edit card was a stub — "{N} paragraphs edited
directly" plus a countdown and a Save-now button. The spec says the
card should grow one inline word-diff per touched paragraph as the
contributor types, in the same green/red register the Phase 3 accepted
overlay uses. Phase 5 lands that.

In RFCView.jsx, the 800ms-debounced handleEditorUpdate now computes a
per-paragraph token diff alongside the existing paragraph count and
stores both on manualPending. Baseline is the same Phase 4 gutter
source — originalSourceLinesRef.current, the last server-confirmed
body split on blank lines — so the card resets to empty the same
moment the gutter clears (accept/decline/manualFlush/branch-switch).

In ChangePanel.jsx, diffWords is exported (it was already the AI
card's inline-diff engine — token-level LCS over a whitespace-
preserving /(\\s+)/ split, ~30 lines, no runtime dep). The manual
card consumes the same tokens. Wholly-inserted paragraphs render as
all-insert blocks; wholly-deleted paragraphs as all-delete blocks.

Visual register is intentionally shared with Phase 3's preview
overlay: same #dcfce7/#166534 inserts, same #fee2e2/#991b1b
strike-through deletes. Selectors are scoped under .change-manual-diff
rather than reusing .markdown-preview .tracked-* since the card lives
outside the preview surface.

Pre-fancy stance, matching Phase 4's gutter: the diff is index-aligned
against the baseline, so adding a paragraph in the middle lights up
the rest of the doc. Tolerated as the "you've touched stuff below this
point" cue. An LCS-anchored future pass can fix it.

Verification gap matching Phases 2/3/4: backend was not running this
session, so the live RFCView → real-branch flow wasn't exercised.
Drove the Vite preview sandbox instead — mounted ChangePanel with a
hand-built diffs payload, confirmed three blocks render (mixed edit,
wholly-inserted, wholly-deleted), inserts/deletes carry the expected
computed colors, no console errors. Backend integration suite still
green (125 passed).
