Adds `web_src/js/utils/func.ts` with `debounce` and `throttle`, dropping
`throttle-debounce` and `perfect-debounce` dependencies. Both were
needed before: the former has no promise-returning debounce, which
`TextExpander` requires, and the latter no `throttle`.
Signature follows lodash and es-toolkit: `(func, wait, {leading,
trailing})` plus `cancel`, so argument order flips at the migrated call
sites.
Extend the issue context popup beyond markdown. Any link rendered with
the `ref-issue` class now gets the popup, which covers commit titles and
issue titles everywhere they appear (repo home, commits list, blame,
branches, graph, PR commits, issue/PR pages, compare, …). For surfaces
that synthesize links without markdown autolinking (dashboard activity
feed, pulse page, commit merged-PR line), opt in by adding
`data-ref-issue-container` on a parent (or `ref-issue` on the link).
- Use `html_url` from the backend payload instead of synthesizing links
client-side
- Fetch outside the component, stateless, with a per-URL cache
- Small hover delay so passing over a link doesn't fire a request
- Drop the loading state (shifted layout)
- Make both links in the tooltip work; prevent nested tooltips
- Fix feed title `<a>` width so the tooltip only shows on link hover
