Adds lsp-plugins 1.1.26 as a new BST element, building only the LV2 format (headless, no GUI) for use with PipeWire filter-chain configs.

lsp-plugins provides a full suite of DSP plugins including parametric EQ, compressor, limiter, gate, bass enhancer, and expander. These load natively via PipeWire filter-chain without Easy Effects or any Flatpak overhead.

The 1.1.x release series is self-contained (no network module fetching at build time). The element uses BUILD_MODULES=lv2 LV2_UI=0 BUILD_R3D_BACKENDS= to produce only the LV2 .so files (~2MB installed). External dependency: freedesktop-sdk libsndfile.

Closes #903

Review Change Stack

Warning

Review limit reached

@castrojo, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 17 minutes and 41 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

Thanks for the PR! A maintainer will review it.

While you wait, make sure these pass locally:

just validate        # element graph check
just build default   # build the image
just boot-test       # confirm the desktop boots (exits 0 = pass)
just lint            # bootc container lint

If this PR fixes a bug, add verify steps to the linked issue so users can confirm the fix on their hardware after the next nightly ships:

```verify
ujust <something>   # what users should run to confirm the fix
```
