YoursFunny 670a7bd02b fix: answer an inline query whose media Telegram cannot fetch
Every item was skipped — `needs_media_headers` for pixiv's pximg.net, or a
local ugoira/bsky MP4 that does not parse as a URL — and the function fell
through to `Ok(false)`, which the debounce reads as "retry this query". The
client got no answer at all (a spinner with nothing behind it) and every
keystroke re-ran the fetch, while an unsatisfiable link is the *permanent*
truth for that query: Telegram fetches inline result URLs itself and never
sends a Referer.

It now answers the empty result set with a 300 s window, so the client stops
spinning and the same query is served from Telegram's cache and from the
debounce (which only releases on a failure). A *failed* fetch still releases,
so a retry is not answered from a stale empty answer.

Verified with a real pixiv link through a real `Bot` against the stand-in
API: `AnswerInlineQuery` with `results: []` and `cache_time: 300` (and
`Ok(true)`, so no release).

`cargo fmt --check`, `cargo clippy --workspace --all-targets --locked -- -D
warnings` and `cargo test --workspace --locked` clean.
