* chore: add prettier config and CI auto-formatter
Adds .prettierrc and .prettierignore (config only, no local enforcement).
Formatting runs in CI via the prettier.yml workflow: on every push to a
non-main branch, Prettier rewrites changed files and commits the result back
using GITHUB_TOKEN. Developers never need to run Prettier locally.
Intentionally excludes husky/lint-staged — local pre-commit hooks are the
wrong layer for a formatter that the whole team doesn't need installed.
Also adds .envrc.local to .gitignore for personal local shell overrides.

Add docs/ for newcomers: an index, an architecture deep-dive (the
OBSERVE→DECIDE→ACT loop, the canonical state model, the package layout, every
component, and the load-bearing invariants), and a status/roadmap (what's done
PR-by-PR, what's left, the integration to-dos + carried-forward items, the open
cross-lane contract questions, and where to plug in). Link them from the README.
