feat: add argument-hint frontmatter to Claude Code commands (#1951) (#2059)

* feat: add argument-hint frontmatter to Claude Code commands (#1951)

Inject argument-hint into YAML frontmatter for Claude agent only during
release package generation. Templates remain agent-agnostic; hints are
added on the fly in generate_commands() when agent is "claude".

Closes #1951

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: scope argument-hint injection to YAML frontmatter only

Addresses Copilot review: the awk/regex matched description: anywhere
in the file. Now both bash and PowerShell track frontmatter boundaries
(--- delimiters) and only inject argument-hint after the first
description: inside the frontmatter block.

* feat: add argument-hint to Claude integration + tests

- Override setup() in ClaudeIntegration to inject argument-hint into
  YAML frontmatter after description: line, scoped to frontmatter only
- Add ARGUMENT_HINTS mapping for all 9 commands
- Add tests: hint presence, correct values, frontmatter scoping,
  ordering after description, and body-safety check

Addresses maintainer feedback to cover the new integrations system
in src/specify_cli/integrations/claude/__init__.py with tests in
tests/integrations/test_integration_claude.py

* fix: address Copilot review feedback on Claude integration

- Remove unused `import re`
- Skip injection if argument-hint already exists in frontmatter
- Add found_description assertion to test_hint_appears_after_description
- Add test_inject_argument_hint_skips_if_already_present test

* refactor: delegate to super().setup() and post-process for hints

- Eliminates setup() duplication by calling super().setup() then
  post-processing command files to inject argument-hint
- Fixes EOL preservation to correctly detect \r\n vs \n
- No drift risk if MarkdownIntegration.setup() changes

* fix: use read_bytes/write_bytes for platform-stable EOL handling

Address Copilot review: avoid platform newline translation by using
read_bytes()/write_bytes() instead of read_text()/write_text() when
post-processing SKILL.md files for argument-hint injection.

* fix: re-record manifest hash after hint injection, quote hint values

- Re-record file hash in manifest after writing argument-hint so
  check_modified()/uninstall stays in sync
- Double-quote argument-hint values to match SKILL.md frontmatter style
- Update tests to expect quoted hint values

* fix: inject disable-model-invocation into Claude skill frontmatter
