* feat: adopt MiniMax-AI OSS patterns into hawk

Verified-net-new improvements identified by scanning MiniMax-AI's open-source
repos and adversarially mapping ideas onto hawk's actual source. Patterns only,
no code copied (all sources MIT).

- exit-code taxonomy: internal/hawkerr/exitcode.go classifies errors into stable
  codes (auth/network/ratelimit/timeout/...) so callers can branch on the
  failure reason instead of a bare 1; wired into cmd/hawk/main.go
- IsTerminal color gate: suppress ANSI/Unicode when stdout is piped (non-TTY),
  fixing ANSI leaking into captured/JSON output; FORCE_COLOR still overrides
- MCP client honors isError: parseToolCallResult surfaces remote tool failures
  as errors the agent can self-correct on
- batch web search/browse: queries[]/urls[] concurrent fan-out (bounded) in
  WebSearch and AgenticFetch; single query/url still works; adds a
  relevance-refusal contract to the AgenticFetch sub-agent prompt
- RiskLevel -> MCP annotations: ToolAnnotations (readOnly/destructive hints) on
  the MCP server's tools/list so clients can self-throttle
- hawk mcp serve / hawk mcp config: run hawk as an MCP server (machinery existed
  but had no entrypoint) and emit the client registration JSON block
- tool-call confusion-matrix eval: internal/feature/eval/toolmatrix.go scores
  trigger (TP/FN/FP/TN, precision/recall/F1) separately from payload accuracy;
  exposed via `hawk eval tools`

All new code is unit-tested; touched packages build, vet, and test clean.


* chore: sync external submodules to latest origin/main

Advance the eyrie and yaad submodule pointers to the current tip of their
origin/main (the other four already matched). Picks up upstream commits that
were present on the remotes but not yet recorded in hawk's index.


* chore: bump eyrie submodule to merged main (efe3710)

Point external/eyrie at the squash-merged eyrie main containing the provider
error/image/reasoning/verify work, so hawk consumes the released eyrie changes.
