fix(schema): allow spreadsheetEvents.operation row_delta to unblock prod Convex deploy

[HomenShum]

P0 — production deploys broken since ~18:37 UTC

vercel-build.sh runs convex deploy on every production build. It has been failing schema validation:

Schema validation failed. Document in table spreadsheetEvents does not match: Path: .operation
Value: "row_delta"
Validator: v.union(set_cell, insert_row, delete_row, add_column, delete_column, apply_formula, add_sheet, rename_sheet)
Error: Command "bash scripts/vercel-build.sh" exited with 1

The live CDN is serving bytes from the last successful deploy (Last-Modified 18:37, ~3.7h stale). Everything merged since 18:37 — #496, #497, #500 (host-write security), #501, #499 (type-scale) — is NOT live.

Root cause

row_delta is a legitimate operation introduced by PR #498 (spreadsheets.ts applyRowDelta + schema literal + test). That feature was run against shared prod Convex out-of-band (the AGENT_COORDINATION hazard), writing a spreadsheetEvents doc with operation: "row_delta" — but #498's schema addition never reached main, so main's validator rejects the doc and blocks all deploys.

Fix

Forward-port the exact literal #498 adds: v.literal("row_delta") into main's union. Additive / expand pattern — non-destructive, reversible, zero conflict when #498 merges (same line). Direct precedent: #477 'tolerate lastActivityAt'.

Verification plan

• CI green (preview Convex deployment has no stray doc, so it always passed — which is why this slipped past CI).
• Real proof: the post-merge production Convex deploy validates the stray doc and succeeds → live URL flips to the new bytes. I'll live-DOM verify after merge.

Follow-ups (flagged, not in this PR)

• The stray prod doc + the out-of-band-write that created it should be reviewed (founder): either let ScratchNode v5 mobile visual reset + integrate scratchnode-public-rooms → main #498 land (brings the emitting code) or clean the doc + contract the literal.
• AGENT_COORDINATION reminder: never run convex dev/deploy against shared prod from a feature worktree.
