feat(mcp): add REST + CLI + stdio surfaces for loopover_plan_repo_issues

[xfodev]

Summary

Adds the missing REST + CLI + local-stdio mirror surfaces for loopover_plan_repo_issues (which shipped as a remote-only MCP tool via Epic #7424): a POST /v1/repos/:owner/:repo/issue-plan-drafts/generate route (gated by requireAppRole + requireSessionRepoAccess, with the explicit_create_requires_dry_run_false create-safety guard), a loopover-mcp maintain plan-issues --goal "..." CLI command, and a loopover_plan_repo_issues stdio tool proxying the route. Dry-run by default; only an explicit {create:true, dryRun:false} reaches the write path.

Testing / coverage

• packages/loopover-mcp/bin/loopover-mcp.ts gets an isProcessEntrypoint() guard so a unit test can import it and drive runCli/maintainCli in-process (the untestable server.connect line is /* v8 ignore */d). test/unit/mcp-cli-plan-issues.test.ts drives the CLI (incl. --help) + stdio tool in-process (both .js and .ts); test/unit/routes-issue-plan-draft.test.ts covers the REST route. Every changed line in routes.ts / spec.ts / loopover-mcp.ts is covered.
• test/unit/mcp-tool-rename-aliases.test.ts's tool-count invariant is bumped 79 → 80 for the new tool.
• CI: packages/loopover-mcp/bin/** is added to the backendConfig path filter in .github/workflows/ci.yml so a change to the ~6.6k-line CLI dispatcher runs the full test suite. Rationale (documented inline): the dispatcher is exercised only via subprocess spawn, so vitest --changed can't reach it from a test file, and since chore(mcp): migrate packages/loopover-mcp from plain .js to real TypeScript #7291 migrated it to .ts-only (no committed sourcemapped .js) a scoped run leaves it at thin in-process coverage that drags the merged global-threshold check under the bar. This is the same reason the migration PR (chore(mcp): convert bin/loopover-mcp.js to TypeScript (Phase 3 of #7291) #7509) touched config paths.

UI Evidence

Data-only change (regenerated apps/loopover-ui/public/openapi.json for the new route) — no rendered UI change; before/after are identical. Captured at each required viewport (loopover-ui is dark-mode-only):

Viewport · Theme	Before	After
Desktop · Dark (1280×800)
Tablet · Dark (768×1024)
Mobile · Dark (375×812)

No visual diff — the change only regenerates the OpenAPI data asset; the homepage renders identically before/after.

Closes #7764

_{(Supersedes #7834/#7846/#7856. Prior closes: base conflict from the loopover-mcp.js removal (now .ts-only), the 79→80 tool-count invariant, and the validate-tests-merge global-coverage trap for loopover-mcp.ts under scoped selection — all addressed here.)}

Review summary
This PR adds a well-structured three-surface (REST/CLI/stdio) mirror for the previously remote-only loopover_plan_repo_issues tool, closely mirroring the existing contributor-issue-draft pattern including its create-safety guard (explicit_create_requires_dry_run_false) and per-repo session gating. The isProcessEntrypoint() guard is a reasonable, well-documented approach to get real in-process coverage of the subprocess-only CLI dispatcher, and the route/CLI/tool wiring (schema, path admission, help text, tool count bump 79→80) all line up consistently across the diff. The codecov/patch failure (48.97% vs 99% target) is the one real gap — a large fraction of the new dispatcher branches (help text, JSON output, error paths) aren't obviously covered by the tests shown.

Blockers

• codecov/patch failed at 48.97% vs the 99% target — given the PR's own stated goal of full coverage on every changed line in routes.ts/spec.ts/loopover-mcp.ts, this is a real, currently-unmet requirement rather than a stale-branch artifact, since the base is only 6 commits behind (routes.ts and spec.ts changes are small and self-contained, so the shortfall likely traces to uncovered branches in the ~100-line loopover-mcp.ts diff, e.g. the catch/realpath-failure paths or CLI arg-parsing edges not exercised by mcp-cli-plan-issues.test.ts).

Nits — 8 non-blocking

• packages/loopover-mcp/bin/loopover-mcp.ts:948-951 — goal max length (2000) and default limit (5) are magic numbers; consider named constants for readability, matching the existing style of documenting them in the comment.
• src/api/routes.ts:2825-2829 — the 400 status literals are fine as-is (Hono convention) but the schema's max(2000)/max(10) constants could be shared with the MCP shape via a single source of truth to avoid drift if either changes.
• The external brief flags a possible secret at test/unit/mcp-cli-plan-issues.test.ts:31 — this is `LOOPOVER_API_TOKEN = "in-process-token"`, a clearly fake test fixture token, not a real leaked secret.
• packages/loopover-mcp/bin/loopover-mcp.ts:2651,3282,3527 use `any` annotations, consistent with the rest of the file's existing untyped CLI plumbing, but worth tightening opportunistically.
• Add/verify a test exercising the realpathSync catch branch in isProcessEntrypoint() (e.g. a removed/renamed argv[1]) since it's currently only defensively commented, not obviously covered.
• Possible screenshot-table issue: identical images (row 1) — Advisory only — verify the screenshot-table images against the stated change before deciding.
• Possible screenshot-table issue: identical images (row 2) — Advisory only — verify the screenshot-table images against the stated change before deciding.
• Possible secret-shaped assignment in the diff (generic_secret_assignment) — Verify the value is not a real credential.

The PR adds a REST route calling generateIssuePlanDrafts gated the same way as the contributor-issue-drafts route, a `maintain plan-issues` CLI command calling that route, and a `loopover_plan_repo_issues` registerStdioTool block proxying the CLI logic, matching all three requested mirror surfaces and the requireRepoManageAccess-equivalent gating pattern.
