chore: delete archive graveyards

[Aviator-Coding]

Intent

Delete both archive graveyards: .archive/ (57 files, 2390 lines) and .github/archive/ (5 files, 5 files total). Pure deletion PR with no other changes. Git history remains as the archive for recovered reference. Re-verified zero inbound references across entire codebase before deletion.

What Changed

• Removed the entire .archive/apps/ tree: retired manifests for ai-system/agentgateway, ai-system/grafana-mcp, gaming/filebrowser, gaming/space-engineers-ds (including its volsync instances/plugins subtrees), and openclaw (homeops-claw, my-claw, operator) - 57 files.
• Removed the entire .github/archive/ tree: retired GitHub Actions workflow files flux-local.yaml, labeler.yaml, pre-commit.yaml, pre-pull-images.yaml, and test-runner.yaml - 5 files.
• No other files were added or modified; this is a pure deletion of 62 files (3134 lines) with the removed content preserved in git history.

Risk Assessment

✅ Low: Pure, verified deletion of two orphaned archive directories with zero remaining inbound references and no changes outside those paths - matches stated intent exactly.

Testing

This is a non-UI, pure-deletion housekeeping change (removing two orphaned archive directories), so there is no rendered surface or unit-testable code path to exercise; the appropriate evidence is structural verification of the diff and reference-freedom, which was performed directly against git and the filesystem. The diff between base and target commits is confirmed to be exactly 62 file deletions (57 in .archive/, 5 in .github/archive/) with no other changes, and a full-tree search (both at the target commit and retroactively at the base commit) turns up zero references to either deleted path anywhere in the remaining codebase, confirming the stated intent (pure deletion, zero inbound references) is satisfied with no regressions.

Evidence: git diff --name-status (base -> target): all 62 changes are deletions, split 57/.archive + 5/.github-archive

$ git diff --name-status 12b2a76a...0ce15b1d | wc -l
62
$ git diff --name-status ... | grep '^D\s\.archive/' | wc -l
57
$ git diff --name-status ... | grep '^D\s\.github/archive/' | wc -l
5
$ git diff --name-status ... | awk '$1!="D"'
(empty - no non-delete changes)

Evidence: Full-tree grep for inbound references to .archive/.github-archive at target commit: zero hits

$ grep -rn "\.archive" --exclude-dir=.git .
(no output)
$ grep -rn "github/archive" --exclude-dir=.git .
(no output)
$ ls .archive .github/archive
ls: .archive: No such file or directory
ls: .github/archive: No such file or directory

• grep -rn "\.archive" --exclude-dir=.git . (target commit, post-deletion tree)
• grep -rn "github/archive" --exclude-dir=.git . (target commit, post-deletion tree)
• git grep -n "\.archive" 12b2a76a45986c7165b157ecbb44fc16d3267752 -- . ':!.archive' (base commit, confirms no prior inbound references)
• git grep -n "archive/" 12b2a76a45986c7165b157ecbb44fc16d3267752 -- .github ':!.github/archive' (base commit)
• ls .archive .github/archive (confirmed absent post-deletion)
• grep -n "archive" .gitignore .pre-commit-config.yaml .renovaterc.json5 (no stale references to clean up)
