docs: sync provider count to 259 (unblocks docs-counts strict gate) (#7616)

* docs: sync provider count to 259 (docs-counts strict gate)

The auto-generated catalog (docs/reference/PROVIDER_REFERENCE.md) is at
259 providers; README.md, AGENTS.md and CLAUDE.md still said 253 —
tripping the strict Provider-count check in check:docs-counts for every
PR targeting the release branch (surfaced red on #7615's Docs Gates
fast-path run). Updates the 8 provider-count mentions across the three
files (marketing badges and AES-256-GCM strings untouched).

* docs(changelog): add fragment for #7616 (provider-count sync)

 **Will I be charged by OmniRoute?** No — it's free, open-source software on your machine. You only pay paid providers directly. OmniRoute has no billing system.
 **Are FREE providers really unlimited?** Mostly — Qoder, Pollinations, LongCat, and Cloudflare are free with no per-account credit cap. Kiro is free too but capped at ~50 credits/month per account. Stack multiple free providers in a combo and auto-fallback keeps you serving for $0.
