Paul BakausandClaude Opus 4.6 a832fe778c No-HMR fallback: fetch raw source and inject variants into DOM ...

For dev servers without HMR (Bun static imports, simple HTTP servers),
the browser can't see file changes automatically. Three changes fix this:

1. /source endpoint on live server: reads a project file from disk,
   gated by session token + path-traversal guard. The browser fetches
   the raw HTML directly, bypassing the dev server's cache.

2. poll --reply --file flag: agent passes the source file path when
   replying done. The browser receives it via WS and knows where to
   fetch. Skill reference updated to always include --file.

3. Browser injectVariantsFromSource(): on "done" with 0 DOM variants,
   fetches the raw HTML from /source, parses with DOMParser, extracts
   the variant wrapper, finds the matching element in the live DOM by
   class/ID, and replaces it. MutationObserver picks up the injected
   variants and the cycling bar appears.

Also: wrap CLI no longer hides the original element (was display:none).
The original stays visible until the first variant arrives, preventing
a flash of empty content between wrap and variant insertion.
