* Add skills specific telemetry
* Remove VisibilityFuture, inline goroutine at call sites
The VisibilityFuture/FetchRepoVisibilityAsync/Wait wrapper was an
unidiomatic async abstraction built for a single pattern used in
exactly two call sites. In Go the channel is already the future;
wrapping it in a struct with a Wait(timeout) method adds no value.
Delete the abstraction and inline a local visResult struct,
buffered channel, goroutine, and select at each call site. Behavior
is preserved exactly: err -> "unknown", timeout -> "unknown",
success+public -> include skill_names.
FetchRepoVisibility (synchronous) is kept as-is.

* Fix nonsense copilot tests
* Update telemetry tests for public-only dims and search event removal
Production telemetry emission changed:
- preview: skill_owner/skill_repo/skill_name (renamed from skill_names)
are now emitted only when repo_visibility=public.
- install: skill_owner/skill_repo/skill_names are now emitted only
when repo_visibility=public.
- search: the initial skill_search event was removed entirely; the
skill_search_install event no longer carries query/owner dims.
Update tests to match: rename skill_names -> skill_name in preview,
make owner/repo assertions conditional on public visibility in both
preview and install, and reduce the search test to a single event
with explicit Empty assertions for the removed query/owner dims so a
privacy regression cannot pass silently.

* Test CategorizeHost and switch telemetry to skill_host_type
Add TestCategorizeHost covering all four classification branches
(github.com, ghes, tenancy, uncategorized) with cases verified
against the real ghauth implementation rather than guessed.
Update install and preview unit tests to assert the new
skill_host_type dimension name, and fix a typo in the preview
acceptance txtar (skill_hos_type -> skill_host_type).

* Shrink visibility wait and test unknown visibility
The 2s visibilityWaitTimeout was wildly overprovisioned: by the time
telemetry emission reaches the select, the command has already done
several serial GitHub REST calls (and for install, a git sparse-checkout
plus possibly interactive prompts), so the one-call visibility fetch
has almost always completed. Drop the timeout to 200ms — a short safety
net for a stalled REST call, not a wait budget for a healthy one.
Also adds a table-driven case to TestFetchRepoVisibility covering an
unknown/future visibility value from the API, addressing @babakks'
review nitpick.

- Keep skillName as bare name in JSON output for backward compat;
namespace is available as a separate --json field
- Fix Namespace field comment to cover plugin namespaces too
- Trim /SKILL.md from install path arg to match comment

tests install disambiguation, not search

Skills with the same name but different namespaces (e.g.
skills/kynan/commit and skills/will/commit) were being collapsed
into a single search result because extractSkillName discarded the
namespace. This also caused deduplicateByName to cap results
across different namespaces as if they were the same skill.
Changes:
- Add MatchSkillPath to discovery package returning both name and
namespace (the existing MatchesSkillPath is kept for compat)
- Add Namespace field to skillResult in search
- Fix deduplicateResults to use repo/namespace/name as the dedup key
- Fix deduplicateByName to cap by namespace-qualified name
- Update table, prompt, and JSON output to show qualified names
- Use skill path for install subprocess when namespace is present,
ensuring unambiguous install of namespaced skills
- Add namespace to --json fields and relevance scoring/filtering
- Add unit tests for namespace dedup, qualified names, and filtering
- Add acceptance test for namespaced skill search and install

When a directory argument is provided to `gh skill publish`, the remote
detection now correctly uses the target directory's git remotes instead
of the current working directory's remotes.
Previously, `detectGitHubRemote` used the factory-provided git client
which pointed to the CWD. This meant that running
`gh skill publish /path/to/repo-bar` from inside repo-foo would detect
repo-foo's remotes and potentially create the release on the wrong repo.
The fix copies the git client and sets `RepoDir` to the target directory,
matching the pattern already used by `detectMissingRepoDiagnostic` and
`checkInstalledSkillDirs`.

refactor: remove Claude plugin branding, align with Open Plugin Spec
Replace all 'Claude plugin' references with generic 'plugin' terminology
to align with the vendor-neutral Open Plugin Spec
(https://github.com/vercel-labs/open-plugin-spec).
Changes:
- Rename .claude-plugin/ to .plugin/ (spec §5.1 vendor-neutral manifest)
- Rename claudePluginJSON/claudeAuthor types to pluginJSON/pluginAuthor
- Rename claudeMarketplaceJSON to marketplaceJSON
- Rename generateClaudePlugin to generatePlugin
- Remove 'Claude Code' from plugin-related comments, help text, and flags
- Update install.go plugins/ convention message
Factual host references (Claude Code as an agent name, .claude/skills
directories) are intentionally preserved — those are product names, not
plugin branding.

- pluginJSON, marketplaceJSON, marketplacePlugin types
- Related tests and help text

GitHub's Artifact API now rejects artifact names like '..' server-side

reproduced through normal artifact creation.
The client-side traversal check in gh run download remains in place as a

Outside of the hostnames previously fixed, I talked with @williammartin about what to do with the remaining references and the concern about the mixed format.
One suggestion for the error / test use case was to remove the extraneous text all together.
There is still a bit of work to get the gh pr comment tests in order, however this goes a way towards fixing the issue along with acceptance tests.
Also, it turns out some of the issue acceptance tests were really running `pr` tests.
The previous commit failed to update the 2nd set of tests to rely upon GH_REPO instead of --repo flag.
These have been tested against `trunk` and fail because not being in a git directory when they should pass.
This commit builds on top of work previously done within acceptance tests around gh secret and remote disambiguation.
The choice of expanding this existing test rather than creating a new test was in order to keep context together within a single acceptance test rather than splitting it over multiple.
`gh repo rename` can only rename a repo, but not change its owner
(i.e. transfer it).
As flagged in #10034, at the moment, the CLI behaves like it can do
this, and produces weird results.
If I ask to rename my repo to `polyseam/frappe-containers`:
```bash
gh repo rename polyseam/frappe-containers
```
..the preview suggests that it will do the right thing:
```
? Rename polyseam/containers to polyseam/frappe-containers? Yes
```
...but the repo gets renamed wrongly:
```
✓ Renamed repository polyseam/polyseam-frappe-containers
```
This adds an upfront validation that looks for a slash and tells
you that the command can't transfer a repo.
Fixes#10034.
