fix: paint first frame for reduced-motion, preserve mobile agent count, cleanups

- terminal.ts: paint one unconditional frame after refit() so reduced-motion
  visitors (and the first rAF before pause fires) always see a mature network
- terminal.ts: capture agentCount at mount time; re-apply after set_preset so
  mobile's 12k override survives preset switches
- tslime-wasm/Cargo.toml: drop silently-ignored [profile.release] (workspace
  profile wins; cargo was warning on every build)
- tslime-wasm/src/lib.rs: doc tick() noting it is a no-op in headless/ANSI mode
- pages.yml: widen path filter to include src/render/** and src/simulation/**
  so wasm rebuilds trigger on any core rendering or simulation change
