Introduce a typed error contract framework for lark-cli so in-process
Go callers can branch via errors.As(&errs.XxxError{}) and shell scripts,
AI agents, and protocol adapters can branch on stable JSON type/subtype
fields instead of regex-parsing free-form messages.
Adds:
- Canonical taxonomy under errs/ (9 categories + typed Error structs
embedding a shared Problem, RFC 7807-aligned)
- Centralized Lark code metadata + identity-aware BuildAPIError dispatch
- Typed JSON envelope writer alongside the legacy envelope writer
- MCP / OAuth (RFC 6750 Bearer) projection adapters
- Five CI lint guards preventing ad-hoc taxonomy drift
Backward compatibility: legacy *output.ExitError producers (ErrAPI,
ErrWithHint, Errorf, ErrBare) and business shortcuts that use them
continue to render the legacy envelope unchanged. SecurityPolicyError
wire format and exit code are preserved via a carve-out; taxonomy
migration is deferred to PR 2. Domain-specific business migration is
staged across PR 3+.
Framework-direct paths now return typed *errs.*Error: ErrAuth /
ErrValidation / ErrNetwork emit category literals on the wire
(authentication / validation / network), *core.ConfigError is promoted
at the cmd/root boundary with exit code aligned from 2 to 3, and Lark
API permission denials classified by BuildAPIError exit 3.
At the SDK boundary, WrapDoAPIError preserves any already-classified
error (legacy *output.ExitError or typed *errs.*) so output.ErrAuth
from missing credentials surfaces with the auth category and exit 3
intact instead of being downgraded to a network error. Policy responses
classified by BuildAPIError (codes 21000 / 21001) extract challenge_url
and the canonical hint from the response body, matching what the
auth transport already surfaces at the HTTP layer; non-https
challenge URLs are dropped.
First PR in the feat/error-contract-* series.
