chore: bump 0.2.5 → 0.2.6 to retry npm publish

v0.2.5 release tagged at a commit before the publish.yml NPM_TOKEN
fallback fix (b8e3464). gh run rerun used the workflow file from
the tagged commit (without the fix), so it failed identically.

Bumping to 0.2.6 and cutting a fresh release from main (which has
the workflow fix). Same source code as 0.2.5 — only difference is
the publish workflow now has NPM_TOKEN auth.
