fix(ci): raise Build/Test/Clippy timeout from 15 to 30 minutes

[logbie]

The clippy-and-test job compiles the workspace three times (debug,
release, and a third release build for the panic=abort assert), runs the
full workspace test suite, builds the LSP binary, and runs Clippy. That
real work now lands right at ~15 minutes even with a warm cache.

As a result, the last two pushes to main both failed CI: the 15-minute
timeout-minutes fired mid-Clippy (run 1a9705a) or during the cache-save
Post step (run 6c9888c), marking the whole job cancelled even though
every real step passed. A cancelled job also skips bump-version, so
post-merge version bumps stopped happening.

Raise the limit to 30 minutes to give headroom for cold-cache builds
while still bounding a genuinely hung job.

Pull request overview

This PR increases the GitHub Actions CI job timeout for the clippy-and-test workflow job to prevent spurious cancellations during long builds/tests/Clippy runs, which can also block downstream jobs like version bumping.

Changes:

• Increased clippy-and-test job timeout-minutes from 15 to 30.
• Added inline rationale explaining why the extra headroom is needed (warm vs cold cache, cancellation side effects).
