sysadminandClaude Opus 4.8 82e6d3a3f4 docs: add subagent tool-budget guardrails for MCP tasks (Closes #259)
Document default tool-call and wall-time budgets for deterministic MCP
work, forbid subagent commit delegation when gitea_commit_files is
available, and pin the rules in runbooks, portable skill, operator guide,
and doc-contract tests.

"""Doc-contract checks for subagent tool-budget guardrails (#259).
Single-step MCP tasks must not expand into 100+ tool-call retry spirals with
WebFetch/Playwright/manual-encoding fallbacks. These tests pin budget defaults,
native-MCP-first rules, and forbidden detours in the runbooks, portable skill,
and operator guide.
