feat(miner-hands): lint-guarded edit wrapper for coding-agent drivers (#4276)

[joaovictor91123]

Summary

• Adds packages/gittensory-engine/src/miner/lint-guard.ts, wrapping a CodingAgentDriver result with the existing per-package correctness check before it reaches the acceptance gate.
• Classifies each changed file into the package whose existing check governs it: apps/gittensory-ui -> ui:typecheck, packages/gittensory-engine -> its own tsc -p tsconfig.json build, packages/gittensory-miner/packages/gittensory-mcp .js files -> node --check (per file), everything else (including non-.js files like hand-written .d.ts under those two packages) -> the root npm run typecheck.
• Runs one check per package group (not one per file) since tsc/ui:typecheck validate a whole package at once — node --check is the one exception, since it's inherently per-file.
• guardCodingAgentDriverResult decorates a CodingAgentDriverResult with the guard's verdict, skipping the guard entirely (empty, passing) when the driver itself failed or reported no changed files.
• No new linter is introduced — this reuses the exact checks the repo already runs in CI.

Test plan

• npx vitest run test/unit/coding-agent-miner.test.ts — 39/39 passing, including the new describe("lint-guarded edit wrapper (#4276)", ...) block covering package classification (all 5 outcomes, .d.ts fallthrough, Windows backslash-path normalization), guardChangedFiles (root typecheck failure, node --check syntax-error failure, clean pass, multi-package changeset checked once per package, same-package grouping), and guardCodingAgentDriverResult (skip-on-driver-failure, skip-on-no-changes, propagate-failure, preserve-fields-on-success).
• npm --workspace @jsonbored/gittensory-engine run build — clean.
• npm run typecheck — clean.
• Isolated coverage of the new file via COVERAGE_NO_THRESHOLDS=1 npx vitest run test/unit/coding-agent-miner.test.ts --coverage --coverage.include="packages/gittensory-engine/src/miner/lint-guard.ts" — 100% statements/branches/functions/lines.
• Did not run the full unsharded npm run test:coverage locally (shared/resource-contended machine); relying on CI's Codecov patch-coverage gate plus the isolated-coverage check above.

Fixes #4276.

🛑 Suggested Action - Reject/Close

• AI reviewers agree on a likely critical defect: The PR description claims the guard sits 'before [the result] reaches the acceptance gate,' but no code in this diff (or referenced elsewhere) calls `guardCodingAgentDriverResult`/`guardChangedFiles` from `coding-agent-invoke.ts`, `driver-factory.ts`, or any gate/acceptance path — the new module is exported from the barrel (packages/gittensory-engine/src/index.ts:192-201) but has zero real callers, so as written it guards nothing
• either point to the wiring commit/PR or add the call site here. — Resolve the flagged defect, or override if the AI reviewers are mistaken, then re-run the gate.

Review summary
Adds a new `lint-guard.ts` module in packages/gittensory-engine that classifies changed files by package and runs the existing per-package check (root typecheck, engine build, ui:typecheck, or per-file `node --check` for miner/mcp JS) via an injected spawn function, plus a `guardCodingAgentDriverResult` wrapper that skips the guard when the driver failed or made no changes. The classification logic, grouping-by-package, and skip conditions are correct and well covered by the 13 new tests (path normalization, multi-package grouping run-once-per-package, failure propagation, driver-failure/no-changes skip paths). The notable gap: nothing in this diff actually calls `guardCodingAgentDriverResult` from the coding-agent invocation path (`coding-agent-invoke.ts` / `driver-factory.ts`) or from any acceptance-gate code, despite the PR description stating the check runs 'before it reaches the acceptance gate' — as shipped, this is an inert, unreferenced utility.

Blockers

• The PR description claims the guard sits 'before [the result] reaches the acceptance gate,' but no code in this diff (or referenced elsewhere) calls `guardCodingAgentDriverResult`/`guardChangedFiles` from `coding-agent-invoke.ts`, `driver-factory.ts`, or any gate/acceptance path — the new module is exported from the barrel (packages/gittensory-engine/src/index.ts:192-201) but has zero real callers, so as written it guards nothing; either point to the wiring commit/PR or add the call site here.

Nits — 5 non-blocking

• packages/gittensory-engine/src/miner/lint-guard.ts:32 — `LintGuardSpawnResult` is exported but never used anywhere in the file (the real spawn results are typed inline via `LintGuardSpawnFn`'s return type) and isn't re-exported from index.ts either; drop it or actually use it.
• packages/gittensory-engine/src/miner/lint-guard.ts:79-86 — `node --check` calls for miner-js/mcp-js files run sequentially in a `for` loop; fine at today's scale but consider `Promise.all` if changesets with many JS files become common.
• No direct test calls `guardChangedFiles([])` — only the driver-result skip path exercises the empty-array case indirectly; worth one direct test since `checks.every(...)` on an empty array trivially returns `ok: true`.
• packages/gittensory-engine/src/miner/lint-guard.ts:74 — for multi-file package checks (root/engine/ui), `file: files.join(", ")` packs multiple paths into one string field; consider a `files: string[]` field instead for cleaner downstream consumption.
• Link or confirm the follow-up PR that wires `guardCodingAgentDriverResult` into the actual driver-invocation/acceptance path — until then this should probably be described as a standalone utility, not as already gating anything.

Why this is blocked

• The PR description claims the guard sits 'before [the result] reaches the acceptance gate,' but no code in this diff (or referenced elsewhere) calls `guardCodingAgentDriverResult`/`guardChangedFiles` from `coding-agent-invoke.ts`, `driver-factory.ts`, or any gate/acceptance path — the new module is exported from the barrel (packages/gittensory-engine/src/index.ts:192-201) but has zero real callers, so as written it guards nothing; either point to the wiring commit/PR or add the call site here.

Addressed
The PR adds lint-guard.ts implementing exactly the corrected scope from the issue: it classifies changed files by package and runs the existing per-package check (root tsc --noEmit, engine's own tsc build, node --check per gittensory-miner/mcp JS file, ui:typecheck for the UI app) rather than introducing a new linter, and returns a structured LintGuardResult/LintGuardedDriverResult instead of thro
