feat(sync): orchestrate prompt synchronization

[ctawiah]

Context

The reconciliation engine produces individual actions, but a complete sync run still needs review, conflict handling, revalidation, and watch behavior. This layer provides that internal orchestration without adding the Cobra command.

What changes

• Reviews and confirms plans before execution.
• Resolves conflicts with LaunchDarkly, local, or abort choices.
• Rebuilds the plan after review so stale decisions cannot be applied.
• Uses fsnotify to watch wrappers and referenced files without an initial sync.
• Debounces file bursts and refreshes an open conflict prompt when sources change.
• Routes command, conflict, result, and watch messages through the shared console writer.

Review focus

• Are interactive and non-interactive paths explicit and safe?
• Does revalidation prevent writes from stale plans?
• Does watch mode handle editor atomic writes and continue after individual failures?

Verification

• go test ./internal/sync/...
• go test -race ./internal/sync/...
• git diff --check

Note

Overview
Adds internal/sync/prompt orchestration for Git-backed prompt sync: a Runner wires bootstrap, link, detach, dry-run, and the full plan → conflict → review → revalidate → execute path.

Interactive flows show per-conflict diffs and prompt for LaunchDarkly, local, or abort; conflicts still require a TTY even with --yes. After review, local/server state is re-read and fingerprint-compared so writes use fresh data; conflict choices are applied on the reloaded plan, not the reviewed copy.

--watch uses direct fsnotify dependency: debounced watches on .launchdarkly and referenced files, content snapshots to ignore duplicate editor events, no sync until the first real change, and automatic plan refresh when sources change during sync or an open conflict prompt.

Interactive forms gain context cancellation via SelectContext / RunFormContext (RunWithContext, alt-screen removed) so watch mode can interrupt huh prompts.

Directory rename drops watch set

Medium Severity

Rename or Remove on a managed directory unregisters that subtree, but relevant ignores those events unless the path is an already-tracked file. When the platform does not also emit per-file events or a Create for the new path, watch stops seeing that tree until some later unrelated sync calls Refresh.
