release v0.0.56

[ranxianglei]

Ships #182 (panel label fixes: never-shrinks wording, cumulative tokensCompressed).

Contents since v0.0.55:

• fix(panel): correct session-accounting label, mark tokensCompressed cumulative #182 — panel.ts/sync.ts/types.ts: label accuracy fixes only, no behavior change

After merge, release.yml publishes 0.0.56 to npm automatically. Then billion-context-pi #268 (already rebased onto v0.1.58, CI green) can merge; a follow-up bcp PR will bump the kernel dep to 0.0.56.

Correction to the release note above: #182 also included a behavior fix beyond the label changes — syncBlocks now keeps host-expanded (user-decompressed) blocks inactive so restored messages are not re-folded next turn (double cost + lost originals); a fresh compress of the same range creates a NEW block. Full details in billion-context-pi#318 which bumps the dep.
