* 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.

runVersionMatchGate and runCanvasStructureGate read locator content with git show/cat-file. For a tag-name locator, `git fetch origin <tag>` only updates FETCH_HEAD and never creates refs/tags/<tag>, so `git show <tag>:...` died with 'invalid object name' and produced a false infra_error.
Read the primary locator via HEAD (already checked out during clone) and non-primary locators via FETCH_HEAD after fetching, instead of the bare locator. This handles SHAs, short tag names, and fully-qualified tag refs uniformly without classifying the locator.
Adds regression coverage for the tag-locator path in both gates.

* Validate canvas extension layout for external submissions
Add intake and quality-gate checks for canvas-tagged external plugins so they must include extensions/extension.mjs and optional manifest extensions is validated when present.

* Fix plugin clean extension pass and typo guard text
Declare EXTENSIONS_DIR in clean-materialized-plugins and run extension cleanup once after plugin cleanup. Also normalize misspelled-key detection strings to satisfy spelling checks without changing validation behavior.

* Proper codespell fix
* Separate canvas structure quality gate status
Track canvas structure as its own gate status and output, include it in aggregate summaries, and enforce Git object types so extensions/ is a tree and extensions/extension.mjs is a blob.
