Marsel Safin 3b7d95a408 fix: rewrite extension-relative subdir paths in generated command bodies (#3444)
* fix: rewrite extension-relative subdir paths in generated command bodies

Extension command bodies reference bundled files relative to the
extension root (agents/, knowledge-base/, templates/, ...). Generated
SKILL.md and command files emitted those paths verbatim, so agents
resolved them against the workspace root where they do not exist.

Add CommandRegistrar.rewrite_extension_paths, which rewrites references
to subdirectories that actually exist in the installed extension to
.specify/extensions/<id>/..., and call it once in register_commands so
every output format and alias gets the fix. commands/, specs/ and
dot-directories are never rewritten.

Fixes #2101

* fix: only rewrite relative extension path references

* fix: use callable re.sub replacement for extension subdir rewrite

subdir and extension_id come from filesystem directory names and were
interpolated into a re.sub string replacement template. A directory name
containing a backslash (e.g. assets\q) would raise re.error: bad escape,
aborting command registration even when the body didn't reference it.
Use a callable replacement so these values are treated literally.

* fix: make subdir rewrite regression test cross-platform

Renamed the test's subdir fixture from "assets\\q" to "assets[q]":
on Windows, backslash is a path separator, so mkdir would create
nested "assets/q" dirs instead of one literally-named directory,
and iterdir() would only discover "assets", never exercising the
rewrite. extension_id keeps a real backslash/"\\1" since it isn't
used to create a directory, still verifying the callable replacement
handles it literally. Added a sanity assertion for this assumption.

* fix: apply extension subdir path rewrite in skills-mode renderer

register_commands() rewrote extension-relative subdir references
(agents/, knowledge-base/, etc.) via rewrite_extension_paths(), but
_register_extension_skills() - the separate renderer used for active
non-native skills agents (e.g. Claude with ai_skills: true) - never
called it. Generated SKILL.md files left agents/... and
knowledge-base/... unresolved, and mapped the extension's own
templates/ through the generic project-level rewrite instead of its
installed .specify/extensions/<id>/templates/ location.

Reuse the existing rewrite_extension_paths() helper in
_register_extension_skills() at the same point register_commands()
applies it (before resolve_skill_placeholders' generic rewrite), and
add a skills-mode regression test.

* fix: apply extension subdir path rewrite on preset restore/reconcile paths

_unregister_skills() restored extension-backed SKILL.md content via
resolve_skill_placeholders() without first calling
rewrite_extension_paths(), so removing a preset override that shadowed
an extension command restored the bare, unresolvable agents/... and
knowledge-base/... references. Carried extension_id/extension_dir
through _build_extension_skill_restore_index() and applied the same
rewrite used at initial registration before restoring.

Found the identical gap in _reconcile_composed_commands()'s non-skill
agent path: when a removed preset's command reverts to an extension
winner, register_commands_for_non_skill_agents() was called without
extension_id, so the rewrite never ran for plain command-file agents
either. Passed extension_id through there too.

Added regression tests for both restore paths (skills-mode and
non-skill-agent command files) in tests/test_presets.py.

* fix: apply extension subdir path rewrite when composing over extension base

PresetResolver.resolve_content() read the effective base layer's raw
content directly via path.read_text() before composing append/prepend/
wrap overlays on top of it, and its outright-replace shortcut did the
same. When that base layer was extension-provided, neither read path
applied rewrite_extension_paths(), so composing a preset over an
extension command (or an extension winning outright through
resolve_content) left bare, unresolvable agents/... and
knowledge-base/... references in the composed output.

All three call sites (PresetManager._register_commands()'s composed
path, _reconcile_composed_commands()'s composed path, and skills-mode
reading the .composed file written by either) consume resolve_content's
return value, so fixing the read at its source covers command output,
skill output, and both initial-install and reconcile flows without
threading extension identity through each caller.

Tagged extension layers in collect_all_layers() with extension_id/
extension_dir, and added a _read_layer_content() helper in
resolve_content() that applies rewrite_extension_paths() whenever a
layer carries that extension identity — used at both raw-read sites
(outright-replace shortcut and composition base). Composing
(append/prepend/wrap) layers are never extension-provided (extensions
are always inserted with strategy "replace"), so no other read site
needs the rewrite.

Added regression tests: a parametrized resolve_content() test covering
append/prepend/wrap composing over an extension base, a skills-mode
test asserting the composed SKILL.md resolves the extension's subdir
references, and a non-skill-agent (Gemini) install-time test matching
the reported live repro.
