* feat(skills)!: promote Skills Repository out of experimental
The registry-backed Skills Repository (crewai skill create/publish/
install/list, @org/name refs, global cache) is now mainline:
- CLI: `crewai skill ...` is a top-level group; the CREWAI_EXPERIMENTAL
gate and the now-empty `crewai experimental` group are removed.
- Runtime: registry.py, cache.py, and events.py move from
crewai.experimental.skills into crewai.skills next to the loader;
the require_experimental_skills() gate is gone.
crewai.experimental.skills remains as a deprecated re-export shim.
- Docs: concepts/skills now leads with the CLI workflow and documents
the create -> publish -> install lifecycle.
Linear: n/a (requested promotion)

* feat(skills): org-scoped publish only + docs in all languages
Skills are always scoped to the publishing organization, like tools:
drop the --public/--private flags from `crewai skill publish` and
always send is_public=False to the registry. CLI tests assert the flag
is rejected and the API never receives a public publish.
Translate the new CLI-first Quick Start and the create -> publish ->
install lifecycle section into ar, pt-BR, and ko concepts/skills docs.

* fix(skills): address review comments on the promotion PR
- Back-compat shim now aliases the old submodules in sys.modules so
`crewai.experimental.skills.registry/cache/events` imports (and patch
targets) resolve to the real crewai.skills modules, not just the
package-root re-exports.
- `crewai skill publish` actually enforces the git-state check that
--force claims to skip: unsynced repos block publishing (mirroring
tool publish); standalone skill dirs outside any git repo publish
without a check.
- Explicit UTF-8 encoding on SKILL.md and cache-metadata reads/writes.

* fix(skills): fail closed when git state cannot be validated on publish
Follow deploy's pattern: construct git.Repository(fetch=False) and only
treat "not a Git repository" as skippable — any other git error
(fetch/auth/misconfiguration) now blocks publish with a --force escape
hatch instead of silently bypassing the sync check.
Also single-style imports in the shim test (CodeQL) with the dotted
shim import covered via importlib.

* fix(skills): fetch before sync check on publish; bump mcp past advisories
Publish now refreshes remote-tracking refs (repository.fetch()) before
is_synced(), so ahead/behind is judged against the actual remote rather
than stale local refs; a failing fetch blocks publish with the --force
escape hatch. Adds a fail-closed test for fetch errors.
Raise mcp to >=1.28.1,<2 (locks 1.28.1): the ~=1.26.0 pin blocked
GHSA-hvrp-rf83-w775 / GHSA-jpw9-pfvf-9f58 (fixed 1.27.2) and
GHSA-vj7q-gjh5-988w (fixed 1.28.1), which were failing pip-audit on
this PR.

* Fix symlink path traversal in skill archive extraction
`_safe_extractall` (the Python < 3.12 fallback used by `crewai skills`
archive unpacking) validated each member's *name* against the destination
but never validated symlink/hardlink *targets*. A malicious skill tarball
could plant a symlink escaping the destination (e.g. `link -> /home/user/.ssh`)
followed by a regular member written through it (`link/authorized_keys`),
escaping `dest` even though every member name resolves inside it — the
classic symlink-extraction traversal.
The 3.12+ path (`extractall(..., filter="data")`) already blocks this; the
fallback now mirrors it by rejecting absolute link targets and any link
target that resolves outside the destination directory.
Adds regression tests covering absolute and relative escaping symlinks plus
benign in-tree symlinks and ordinary archives.
