chore: bump @daily-co/daily-js to 0.91.0, release v2.6.0 (#164)

Bump @daily-co/daily-js from ^0.85.0 to ^0.91.0 (Daily's current latest
stable) and release @vapi-ai/web v2.6.0. Build and unit tests pass; a live
call was verified against the local tarball with clear audio.

Note: daily-js 0.89 changed audio-processor failure behavior — the mic no
longer auto-mutes when the noise-cancellation processor fails. We accept
Daily's new default (no code change).

Supersedes the stale automated #159 (which only bumped daily-js to 0.89.1).
