Tim Mulholland 63c2527ace Accept nested extensions/<name>/extension.mjs in external-plugin canvas checks (#2403)
* Accept nested extensions/<name>/extension.mjs in external-plugin canvas checks

The external-plugin canvas structure check (quality gate) and intake
validation both hardcoded a flat extensions/extension.mjs entry point,
falsely rejecting the documented nested extensions/<name>/extension.mjs
layout that installs and runs fine.

Scan the extensions/ directory for a nested subfolder containing
extension.mjs while still accepting the flat form for backward
compatibility. Applied to both runCanvasStructureGate (git-object
lookups) and validateCanvasPluginMetadata (Contents API), keeping them
behaviorally aligned. Added regression coverage for both paths.

Fixes #2402

* Harden nested canvas extension detection after adversarial review

Address multi-model review findings on the nested canvas extension fix:

- Quality gate: enumerate extensions/ via 'git ls-tree -z' with spawnSync (NUL-delimited, untruncated) so large directories no longer drop the real entry past the 12KB output cap.

- Intake: decouple the flat extensions/extension.mjs check from the directory listing, require an array listing (Array.isArray) before treating it as a directory, and surface an unverifiable (warning) result instead of a false rejection when the listing or a nested lookup hits a transient API error.

- Add regression tests: nested entry beyond the legacy output cap (gate) and unverifiable/flat-still-accepted paths when the listing errors (intake).

* Enumerate canvas extensions via a single recursive Git Trees call in intake

Address PR review: the Contents API caps directory listings at 1,000 entries and required one request per extension subfolder, so a nested entry beyond the cap could be falsely rejected (the same truncation class the git gate avoids) and large repos risked latency / rate-limit exhaustion.

Replace the per-subfolder Contents API enumeration with one recursive 'git/trees/<locator>?recursive=1' fetch and inspect 'extensions/extension.mjs' and immediate 'extensions/<name>/extension.mjs' paths locally. A truncated tree without a located entry point is reported as unverifiable (warning) rather than rejected, and refs are normalized so 'refs/tags/<tag>' resolves as a tree-ish.

* Bound canvas extension discovery to plugin scope

Address reviewer feedback on unbounded scaling for untrusted/large repos:

- Quality gate: replace the per-candidate-directory git cat-file spawns in
  locateCanvasEntryPoint with a single recursive git ls-tree over the
  extensions subtree, classifying flat/nested entry points in memory. Process
  count is now constant regardless of how many folders live under extensions/.

- Intake: stop fetching the recursive git tree from the repo root (which a
  large unrelated monorepo can push past the Trees API truncation limit and
  never validate). Walk to the plugin's extensions directory one level at a
  time to resolve its tree SHA, then fetch only that subtree recursively, so
  verifiability depends on the plugin's own size, not the whole repository.

Install a Plugin

For most users, the Awesome Copilot marketplace is already registered in the Copilot CLI/VS Code, so you can install a plugin directly:

copilot plugin install <plugin-name>@awesome-copilot

If you are using an older Copilot CLI version or a custom setup and see an error that the marketplace is unknown, register it once and then install:

copilot plugin marketplace add github/awesome-copilot
copilot plugin install <plugin-name>@awesome-copilot
