fossil settings: crlf-glob extended to src/vendorlib/* and src/vfs/*

Vendored library payloads and vfs kit payloads legitimately carry CRLF
endings (upstream files are kept as-is; the LF preference governs authored
text). Without the globs, large vendor/vfs checkins block on fossil''s
interactive CRLF prompt - the tablelist 7.11 catch-up (fossil 3316d3c7)
had to use --no-warnings. Policy documented in .fossil-settings/AGENTS.md
alongside the binary-glob rationale. crlf-glob is fossil-only (no
.gitignore-style counterpart), so no dual-VCS derivation applies.

 ### Commit warning suppression
 
 - `binary-glob` is `*`: binary checkins are allowed by default with no fossil warnings/prompts (applies to punkshell and is the pattern for sub-projects like tomlish). The aim of an eventually binary-free tree (goals G-004/G-005/G-006) is agent/workflow policy (see root `AGENTS.md` User Preferences) and is deliberately NOT enforced at the local VCS layer.
+- `crlf-glob` covers `src/embedded/*`, `src/vendorlib/*` and `src/vfs/*`: generated docs, vendored library payloads and vfs kit payloads legitimately carry CRLF endings (vendor files keep upstream endings; the root `AGENTS.md` LF preference governs authored text files). Without this, large vendor/vfs checkins block on fossil's interactive CRLF prompt (observed 2026-07-15 with the tablelist 7.11 payload - that checkin needed `--no-warnings`). If a new payload tree outside these globs trips the prompt, extend the glob rather than reaching for `--no-warnings`.
