xuanandshangguanxuan.sgx da2522c8ca feat(pat)!: A-core loop for host-owned PAT (#142)
* feat(pat): A-core minimum viable loop for host-owned PAT

Enables third-party agents to integrate PAT via the smallest possible
contract surface. The flow a host needs to ship end-to-end:

  1. Export DINGTALK_DWS_AGENTCODE in the spawned shell.
  2. Run any `dws ...` business command.
  3. On PAT hit, CLI exits with code 4 and writes a single-line stderr
     JSON following docs/pat/contract.md §2.
  4. Host parses the JSON and invokes `dws pat chmod <scope>...
     --agentCode ... --grant-type ...` to grant.
  5. Host replays the original command.

This PR intentionally ships ONLY the chmod path plus the host-owned
switch; the async flow (apply / status / scopes + authRequestId
registry + PAT_SCOPE_AUTH_REQUIRED active-request branch) lands in a
follow-up stacked PR (A-ext).

Scope of A-core:
- Host-owned PAT trigger: auth.HostOwnsPATFlow() keyed exclusively on
  DINGTALK_DWS_AGENTCODE (DINGTALK_AGENT / DWS_CHANNEL / claw-type do
  NOT participate).
- claw-type: hard-wired to "openClaw" in pkg/edition/default.go
  MergeHeaders hook, matching historical main behavior and decoupled
  from DINGTALK_AGENT.
- dws pat chmod: factory-built (newChmodCommand) so the PAT subcommand
  tree has no shared package-level caller.
- stderr JSON classifier: internal/errors/pat.go covers PAT_NO_PERMISSION
  / PAT_LOW_RISK / PAT_MEDIUM_RISK / PAT_HIGH_RISK / PAT_SCOPE_*
  selectors and fills data.hostControl for host consumption.
- Env contract: DINGTALK_SESSION_ID / DINGTALK_TRACE_ID /
  DINGTALK_MESSAGE_ID carry HTTP trace headers (Chain B);
  DWS_SESSION_ID (+ REWIND_SESSION_ID alias) is the lone fallback for
  `dws pat chmod --session-id` (Chain A). The two chains are
  independent; aliases do not cross-pollinate.
- Docs: docs/pat/{README,contract,host-integration}.md + refreshed
  docs/architecture.md "PAT Architecture" chapter + docs/reference.md
  PAT section. error-catalog.md folded into contract.md §6.
- Tests: host-owned signal, stderr contract, classifier, chmod factory,
  retry / poll loop for the CLI-owned chmod path.

Compatibility: no breaking changes on main. All non-PAT commands are
untouched.

Follow-up PRs (in order):
- codex/pat-ext  : dws pat apply / status / scopes + AsyncRegistry.
- codex/pat-oss-refactor (aka PR B) : oauth_helpers / secure_store
  refactors split out per code review.

Made-with: Cursor

* fix(pat): unify host-owned stderr contract

* revert: drop PAT docs and changelog from pat core PR

* fix(pat): pin behavior auth endpoint

* fix(pat): recognize legacy tool miss

* fix(pat): fallback on gateway diagnostics

* fix(pat): treat authorization uri as opaque

* fix(pat): accept result envelope in device-flow polling

* feat(pat): add browser policy and poll compatibility

* fix(pat): keep CLI and host PAT contracts separate

* test(pat): isolate opaque uri retry env

* fix(pat): harden PAT result routing

* fix(pat): harden host-owned flow and runtime fallback

* fix(pat): preserve chmod failure on empty grant result

* refactor(pat): drop dead doc anchors, dedupe stderr injection helpers

Address two reviewer findings on top of the PAT-core series.

Fix:
- chmod: resolveSessionIDFromEnv silently selects DWS_SESSION_ID; drop
  the slog.Warn that emitted both raw session ids into stderr /
  ~/.dws/logs.
- Remove every docs/pat/contract.md / error-catalog.md /
  host-integration.md anchor from comments, help, and tests; those
  files were never added by this branch. Comments are now self-contained
  or point to docs/reference.md where applicable.

Refactor:
- internal/errors/pat.go: extract lookupCodeIn so getPATErrorCode and
  getDWSGatewayErrorCode share one traversal; have ClassifyPatAuthCheck
  delegate to getPATErrorCode instead of repeating the enum walk.
- internal/errors/pat.go + internal/app/pat_auth_retry.go: extract
  ApplyHostMutations as the single injection point for data.hostControl
  + data.openBrowser; cleanPATJSON and enrichPATErrorForHostControl now
  share it so the two stderr-JSON write paths cannot drift.
- internal/app/pat_auth_retry.go: drop buildPATScopeHostJSON and
  buildHostControlState dead 1-line wrappers.
- internal/pat/chmod.go: drop unused patApply/Status/Scopes constants;
  derive legacyToolArgs from toolArgs by clone + scopes->scope rename so
  the two payloads stay in lock-step on every other field.

Net 15 files, +176 / -193. Verification:

  env -u DINGTALK_DWS_AGENTCODE go test \
    ./internal/errors ./internal/auth ./internal/pat ./test/unit
  env -u DINGTALK_DWS_AGENTCODE go test ./internal/app \
    -run 'Test(IsPat|ExtractPat|PrintPat|PollPat|HandlePat|RetryWithPat|EnrichPAT|BuildPAT|DirectRuntime|ResolveIdentityHeaders)'
  env -u DINGTALK_DWS_AGENTCODE go test -race \
    ./internal/pat ./internal/errors ./test/unit
  env -u DINGTALK_DWS_AGENTCODE go test -race ./internal/app \
    -run 'Test(HandlePat|RetryWithPat|EnrichPAT|BuildPAT|ResolveIdentityHeaders|DirectRuntime)'
  go vet ./... && go build ./...

All green.
