* refactor(backend): LLD maintainability fixes in controllers/service layers
Addresses the high + medium severity findings from the LLD review of
backend/internal/httpd and backend/internal/service (#95):
1. Controllers no longer import internal/session_manager. Session sentinel
errors are now *domain.ServiceError values carrying their own HTTP mapping,
so the controller translates them with one generic errors.As — no
cross-package sentinel imports.
2. One error pattern across services: project.Error is now an alias of the
shared domain.ServiceError, and session_manager sentinels use it too. A
single writeServiceError replaces the per-resource error switches.
3. Clean-orchestrator business logic moved out of the controller into
session.Service.SpawnOrchestrator(ctx, projectID, clean).
4. isGitRepo no longer treats case-different paths as equal on case-sensitive
filesystems; case-insensitive compare is gated to darwin/windows via samePath.
5. Project repo check sits behind an injectable GitChecker, so the service is
testable without a real git binary.
6. httpd exports only the production constructors (NewWithDeps,
NewRouterWithControl); the 3 test-only wrappers are removed and the
"router with empty deps" convenience moved to an unexported test helper.
Closes#95

* refactor(backend): standardize service errors on internal/httpd/errors
Replace the domain.ServiceError approach with a REST-API-scoped error package
and a single envelope renderer, per review feedback:
- Add internal/httpd/errors (package errors, aliased apierr): one structured
Error type with semantic Kinds (Internal/Invalid/NotFound/Conflict) and
constructors. Imports nothing, so any layer can depend on it.
- envelope.WriteError is now the single path from a service error to the wire
APIError, and the only place a Kind becomes an HTTP status/word. The
per-resource writeProjectError/writeSessionError translators are gone.
- Delete domain/errors.go (keeps domain pure of HTTP-flavored kinds) and
service/project/errors.go (no per-service error files); services build
errors inline via apierr constructors.
- session_manager sentinels are apierr.Error values (pointer identity still
works with errors.Is).

* revert(backend): drop GitChecker seam and isGitRepo case-sensitivity change
Defer findings #4 (isGitRepo case-sensitivity) and #5 (GitChecker seam) out
of this PR. Restores the original exec-based isGitRepo and the New(store)
constructor; removes git.go, git_test.go, and the test-only export shims. The
error-standardization and other findings are unaffected.

* refactor(session): translate engine errors to API errors at the facade
The session_manager is the internal command engine and must not depend on the
REST API error vocabulary. Revert its sentinels to plain errors.New values and
move the engine→API translation into the service/session facade (toAPIError),
which is the correct boundary. Controllers still see apierr.Error and never
import the engine; the engine no longer imports internal/httpd/errors.

* style(envelope): make KindInternal an explicit case in httpStatus

* refactor(apierr): rename package, test SpawnOrchestrator, parity fixes
Address review feedback on PR #96:
- Rename internal/httpd/errors → internal/httpd/apierr (package apierr) so
importers no longer alias around the stdlib errors package.
- Add a commander seam to session.Service and unit-test the relocated
clean-orchestrator rule: clean=true kills all active orchestrators before
spawning; clean=false spawns without kills.
- project.Add: wrap the UpsertProject store error in apierr.Internal for parity
with its sibling paths (was a raw 500).
- Document that KindInternal is iota's zero value, so a zero-value Error
defaults to 500.

* feat(api): register PR action route shells (merge + resolve-comments)
Adds two 501 Not Implemented route shells for the SCM/PR action lane
as specified in issue #21. No business logic — the routes are stubs
that return a structured planned body with the embedded OpenAPI spec
slice, consistent with the existing route-shell pattern.
Routes registered:
POST /api/v1/prs/{id}/merge
POST /api/v1/prs/{id}/resolve-comments
Closes part of #18.

* feat(api): PR action routes — full impl (merge + resolve-comments)
Builds the two SCM/PR action routes end-to-end per issue #21:
POST /api/v1/prs/{id}/merge
POST /api/v1/prs/{id}/resolve-comments
**ports/scm.go** — new PRService interface, MergeResult, ResolveResult.
**adapters/scm/github** — adds ErrNotMergeable/ErrUnprocessable sentinels
to the client (405/409/422 classification) and MergePR / ListUnresolvedThreadIDs /
ResolveThread methods to the Provider.
**internal/scm/pr_service.go** — concrete PRService over PRProvider. Parses
the path ID as a PR number, calls the provider, maps github sentinel errors to
domain errors (ErrPRNotFound / ErrPRNotMergeable / ErrPRPreconditions /
ErrNothingToResolve). Nil PRService keeps routes registered but returns
OpenAPI-backed 501s.
**httpd/controllers/prs.go** — real handlers; writePRError maps the four domain
errors to 404 / 409 / 422 / 500.
**prs_test.go** — httptest coverage: 501 (nil service), 200/404/409/422 for
both routes, spec-slice present in 501 body.
**scm/pr_service_test.go** — table-driven unit tests with a fake PRProvider.
Closes part of #18. Closes#21.

* feat(api): PR action routes — merge + resolve-comments (#21)
Implements POST /api/v1/prs/{id}/merge and POST /api/v1/prs/{id}/resolve-comments.
Service logic lives in internal/service/pr (ActionManager interface + ActionService
struct). Controllers use the projects pattern — import the service package directly
rather than going through a ports interface. Drops the internal/scm intermediary
package and the ports/scm.go file added in earlier iterations.
Also fixes the ContentLength-based body-decode guard in resolveComments, which
silently dropped JSON bodies sent with chunked transfer encoding; now decodes
unconditionally and treats io.EOF as an absent body.
Closes#21.

* fix(specgen): remove dead path-param entries from schemaNames
ControllersProjectIDParam, ControllersSessionIDParam, and ControllersPRIDParam
are never matched by the schemaName interceptor — swaggest reflects path-param
structs inline rather than as $ref component schemas, so the hook is never
called for these types.

* fix(pr): anchor resolve-comments to stated PR when explicit IDs supplied
When commentIDs were provided, the parsed PR number was never used — any
thread ID could be resolved regardless of which PR was in the URL path.
Add a ListUnresolvedThreadIDs existence probe in the else branch so the PR
must be reachable before iterating the caller-supplied IDs.

* fix(controllers): exclude io.ErrUnexpectedEOF from isEmptyBody
A truncated body (e.g. {"commentIds":["T_1") returns io.ErrUnexpectedEOF,
not io.EOF. Treating it as an absent body caused the handler to fall through
to "resolve all unresolved threads" instead of returning 400. Only io.EOF
(reader returned no bytes) is a genuine empty-body signal.

* refactor(api): revert to route shell — stubs, no adapter changes
- Remove adapter changes (ErrNotMergeable/ErrUnprocessable from client.go,
MergePR/ListUnresolvedThreadIDs/ResolveThread from provider.go)
- ActionService returns dummy values with TODO; no business logic
- Errors (ErrPRNotFound etc.) moved to controllers/errors.go
- PR DTOs moved to controllers/dto.go
- Remove 501 guards — stub service always wired via NewAPI default

* fix: restore client.go, move PR errors to service/pr, fix lint
- Restore original client.go alignment (no functional change)
- Move PR sentinel errors to service/pr/errors.go
- controllers/errors.go now only contains writePRError, referencing prsvc sentinels
- Fix schemaNames alignment in specgen/build.go (goimports lint)

* fix(api): replace fake-success stub with 503 when SCM not configured
The nil-service fallback was silently injecting a stub that returned
fake merge/resolve success, misleading callers when no SCM is wired.
Remove the injection; nil Svc now returns 503 SCM_NOT_CONFIGURED.
Also inline writePRError into prs.go and delete controllers/errors.go.

* fix(specgen): mark resolve-comments request body as optional
reqBody: nil removes the requestBody.required: true annotation so
generated SDK clients can omit the body (which resolves all threads).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(prs): align nil-service guard with spec (501) and echo prID in stub
Use apispec.NotImplemented (501) instead of 503 so nil-service responses
match the OpenAPI spec and generated clients hit the documented 501 branch.
Echo prID as PRNumber in the stub Merge to avoid claiming the wrong PR
was merged if NewActionService is wired by accident before real impl lands.
