### What this PR does

Before this PR:
- Plugin detail modal text was not selectable, making it hard to copy
plugin names or descriptions
- Searching for plugins/skills with hyphens or underscores (e.g.
`web-search`, `code_review`) returned zero results because the API uses
word-based matching
- The search placeholder and "no results" message always said "plugins"
even when browsing the skills tab

After this PR:
- Plugin detail modal content is now selectable (added `select-text` CSS
class)
- Search queries automatically normalize hyphens/underscores to spaces
before sending to the API, improving search hit rate
- Search placeholder and empty state messages are context-aware: show
"Search skills..." / "No skills found" on the skills tab, and "Search
plugins..." / "No plugins found" on the plugins tab

### Why we need it and why it was done in this way

The following tradeoffs were made:

- make PluginDetailModal content selectable via select-text class
- normalize search query by replacing hyphens/underscores with spaces to
avoid zero results when API does word-based matching
- add separate i18n keys for skills vs plugins (search placeholder, no
results message) in en-us, zh-cn, and zh-tw locales

The following alternatives were considered:

- Could have added `user-select: all` globally, but `select-text` is
more scoped and follows the existing pattern in the codebase
- Could have done fuzzy matching client-side, but normalizing the query
before sending to the API is simpler and leverages existing server-side
search

Links to places where the discussion took place: <!-- optional: slack,
other GH issue, mailinglist, ... -->

### Breaking changes

None. All changes are additive (new i18n keys, CSS class addition, query
normalization).

### Special notes for your reviewer

- The regex `[-_]+/g` in `MarketplaceService.ts` replaces consecutive
hyphens/underscores with a single space, which should cover common
plugin naming patterns like `web-search` or `code_review`
- Only en-us, zh-cn, and zh-tw locale files are updated; other locales
will fall back to the existing `plugins.*` keys
