Miguel PalhasandClaude Opus 5 9ba1078386 feat(maestro): port the structured pane to React
Closes #246. The transcript, composer and approval controls move from
structured.ts/structuredRender.ts into components under
web/src/components/structured/, against docs/STRUCTURED-VIEW.md: eight row
kinds, both projections, the single-active approval nonce, and diff rendering
with its own line counts.

The pure layers stay shared — structuredDiff.ts computes the diff,
structuredRender.ts still sanitizes markdown — and model.ts holds the
client-side decisions (activity grouping, notice classification, offered
decisions, `/` completion) so they are testable without a DOM.

Like TerminalPane, the pane draws the body only; pane chrome reads the
connection through onStatusChange.

// React port of ../../spawnForm.ts: the spawn form itself — preset tiles,
// two-step project picker, name, structured-view checkbox, worktree. Mounted
// inside SpawnModal.
//
// Working-directory picker (#95), unchanged from the vanilla form:
// 1. Step one is one box per repository (name, then its parent directory).
// A worktree is a box only when its main checkout is missing from the
// scan.
// 2. The filter keeps a repository when the query matches it or any of its
// worktrees.
// 3. Picking a box reveals step two: "+ new", then that repository's
// worktrees newest-first. "Other directory…" clears both steps.
// 4. "+ new" is the default selection — except on a box that is itself a
// linked worktree, which defaults to that worktree.
// 5. "+ new" means create: cwd is the repository, create-worktree on. An
// existing worktree means run in it: cwd is that worktree, create-worktree
// off (the daemon never adopts, docs/WORKTREES.md).
// 6. Neither step probes /api/gitroot; only the free-text hatch does.
