docs: one AGENTS.md for every agent, a roadmap, and docs that match the code

- AGENTS.md holds the engineering rules for any coding agent, plus the
  repo map, build, patch and test commands that CLAUDE.md used to carry.
  CLAUDE.md now only imports it, so there is one set of rules.
  ci/tribal-rules.yml is the record of settled decisions it points to.
- ROADMAP.md lists planned work, each item linked to its issue.
- README:
  - fpgen and the coherence check replace BrowserForge;
  - the patch workflow uses the make targets instead of the removed
    developer UI;
  - letter-spacing noise is described as off by default, as it is.
- docs/:
  - beta-testing-ff146.md removed;
  - patch-upgrading-guide rewritten around the make targets;
  - per-context-patches without the canvas patch that no longer exists,
    and with measured preset counts;
  - playwright-maintenance without the JSM wrapper that does not exist;
  - smaller fixes in MEDIA-DEVICES, input-dispatch and FONTS.
- ci/README: every job, and the real shard, skiplist and entry-point lists.
- pythonlib, tester and patch-dependency READMEs corrected against the code.
