* refactor(ci): move icon preview markup into a composite action
Move generateChangedIconsCommentMarkup.mts into .github/actions/icon-preview
as its own pnpm workspace package, following the suggest-metadata action.
svgson and @lucide/helpers are now real dependencies installed with a
filtered pnpm install, replacing the ad-hoc `npm install svgson --force`.
Paths are resolved from the repo root relative to the script, so it also
works through `pnpm --filter @lucide/icon-preview-action start`.

* fix(ci): skip icon preview comment when no icons changed
When a pull request only deletes icons, CHANGED_FILES has no SVGs and the
script printed "No changed icons found" to stdout, which was then posted as
the preview comment.
The script now logs that to stderr. The action writes no markup file and
sets `has-changes=false`, the workflow skips the artifact upload, and the
comment workflow skips its steps when no artifact exists instead of failing
on the missing artifact.

* ci(icon-preview): post the preview comment from a pull_request_target workflow
Like the PR title workflow, the icon preview now runs on pull_request_target
and posts its comment directly, so comment-icon-preview.yml and the
workflow_run artifact hand-off are removed.
The job checks out the base branch and runs the action from there. The
changed SVGs are read from the pull request head with `git fetch` + `git show`
into a temp directory, so no code from the pull request is checked out or run.
File names are checked against `icons/<kebab-case>.svg` before use.
