Update Docs

Post-change documentation sweep. Captures non-obvious knowledge into the right docs, trims bloat, and keeps the repo's documentation surfaces aligned after changes that likely introduced drift.

When to use

• After infrastructure, configuration, architecture, or operational changes
• After a merged PR, release cut, feature shipment, or version bump when those changes likely caused doc drift
• When asked to refresh docs, instruction files, runbooks, changelogs, API docs, roadmaps, or README content
• When a session uncovered new gotchas, changed setup steps, changed external behavior, or added services
• When an API contract, feature surface, migration path, or release/install path changed
• When the repo's docs surface is obviously underspecified and it is worth suggesting a minimal docs bootstrap to the user
