Description

Prerequisite for #5168, split out as requested in this review and per the integration delivery boundary.

post_process_command_content() is the only per-integration hook that CommandRegistrar.register_commands() calls, and it only sees the rendered text. It cannot tell whether a command came from core or from an extension or preset, and it runs after $ARGUMENTS and __SPECKIT_COMMAND_*__ tokens are resolved. A rewrite that depends on the command's source therefore has nowhere to go except an agent-name branch inside the registrar (today, is_cline_ext in agents.py).

This PR adds IntegrationBase.process_registered_command(frontmatter, body, *, source_id) -> (frontmatter, body):

• register_commands() calls it for every command it registers for the integration, after script-path adjustment and name injection, and before $ARGUMENTS conversion, __SPECKIT_COMMAND_*__ resolution and rendering, so aliases and every output format (Markdown, TOML, YAML, SKILL.md) use the result.
• The default returns both values unchanged, so no integration's output changes in this PR.
• The existing is_cline_ext branch is left as is here; fix(cline): keep .md extension on speckit.* file names in command bodies #5168 moves it into the Cline integration through this hook.

Testing

• New tests/test_registered_command_hook.py (6 tests): the default is a no-op and default registration output is unchanged; an overriding integration receives the parsed frontmatter, the raw body (before $ARGUMENTS conversion) and source_id ("core" and an extension id), and its result is what gets written, including for a skills-layout agent and for aliases. 5 of the 6 fail on main (the hook does not exist); all pass with this change.

• pytest -n 8 tests/integrations tests/test_post_process.py tests/test_extensions.py tests/test_registered_command_hook.py: 3708 passed, 8 skipped.

• uvx ruff@0.15.0 check src tests: clean.

• Tested locally with uv run specify --help

• Ran existing tests with uv sync && uv run pytest (the subset above)

• Tested with a sample project (if applicable)

🟡 Changes recommended

The hook test cannot detect incorrect argument-conversion ordering because OpenCode leaves $ARGUMENTS unchanged and the fixture lacks a command-reference token.
