* docs: sync to Claude Code v2.1.176
Fix the subagent-nesting self-contradiction in 04-subagents and document
additive features shipped in v2.1.172-v2.1.176:
- 04-subagents: subagents can now spawn subagents (up to 5 levels, v2.1.172),
replacing the stale "no nested spawning" line; footer bumped to 2.1.176
- 07-plugins: /plugin marketplace search bar (v2.1.172)
- 10-cli: new settings.json keys wheelScrollAccelerationEnabled,
footerLinksRegexes, language (v2.1.174-v2.1.176)
- 09-advanced-features: enforceAvailableModels managed setting (v2.1.175)
- 06-hooks: if-condition tool-argument path matchers (verified against the
official permissions reference)
- claude_concepts_guide & CATALOG: subagent nesting note + VSCode /usage
attribution breakdown (v2.1.174)
* fix(10-cli): correct language setting scope and fix link-checker false positive
- check_links.py: skip bare-hostname captures (no dot in host) that URL_RE
truncates from regex strings in JSON config examples, e.g.
"https://jira\\.example\\.com/.*" was captured as "https://jira" and
flagged as a dead link in CI strict mode. Dotted hosts (real URLs) and
SKIP_DOMAINS single-label hosts are unaffected, so no link coverage is lost.
- 10-cli/README.md: language is Claude's general response/voice-dictation
language setting (e.g. french/japanese), which v2.1.176 also wired to
session-title generation — not a session-titles-only key. Updated the
description and the JSON example value to match the official settings docs.
* chore(idd): exempt docs-sync PRs from traceability Closes #N requirement
Adds .gitissue.yml so 'docs: sync to Claude Code vX' PRs (which aren't tied to
a single tracked issue) are not hard-blocked on a missing Closes #N — they opt
in via a 'Type: docs' body line, matching how chore/refactor PRs work. The
other three traceability checks still run.
