4.92.0

(feat): fern automations generate now writes a richer GitHub Actions step summary. The summary is an HTML table grouped by API and generator group (with rowspan cells), a heading that shows the succeeded/total count on failure, a duration column, and a links column with the PR, SDK repo, and generators.yml entry (the latter deep-linked to the exact line when running under GitHub Actions). Generators excluded from automation now surface as explicit skipped rows with reasons (Skipped - local output, Skipped - opted out), replacing the silent drop.
