docs(coding-agent): correct js-debug runtime + extraction path per review

Two wording fixes for PR #7759 review:
- debug.md no longer requires `node` on PATH; documents that the adapter
  runs under node if available, else the omp Bun host, matching
  resolveDefaultJsDebugAdapter()'s process.execPath fallback.
- The unavailable message and CHANGELOG now say "extract under
  ~/.local/opt" (not "to ~/.local/opt/js-debug/"), so the archive's
  js-debug/src/dapDebugServer.js lands at the auto-discovered path
  instead of one directory too deep.

Refs #7757.

## Notes
- `packages/coding-agent/src/prompts/tools/debug.md` tells the model only one active root session is supported. Adapter-requested child sessions belong to that root tree.
- The default JavaScript/TypeScript adapter runs vscode-js-debug's `dapDebugServer.js` over TCP.

- Any other location via `JS_DEBUG_DAP_SERVER=<path-to-dapDebugServer.js>`.
- The adapter runs under `node` if on `PATH`, otherwise under the omp host (Bun); `resolveDefaultJsDebugAdapter()` falls back to `process.execPath`, so a Bun-only setup is supported.
- `configurationDone` is sent automatically during root and child launch/attach handshakes and lazily before later requests if the initial handshake did not complete.
- `startDebugging` reverse requests create recursive child sessions on the same TCP server; a stopped child becomes the target for thread-level actions.
- `output` exposes the active session’s merged `output` event stream only; the tool does not distinguish stdout, stderr, and console categories.
