docs(agents): sync shared working rules from ai-rules
Updates this repository's copies of Josh's shared working rules to the current reviewed public projection from BigSimmo/ai-rules (generated by repository_rule_targets.py, the same logic as sync.sh --repos).
Changed: only the managed shared-cloud-working-rules block in AGENTS.md and the shared prefix of docs/agents/shared-context-and-memory.md. Any project-owned addendum is preserved byte-for-byte; the generator refuses to overwrite unreviewed edits.
Main additions: authorized browser/device testing preference (Chrome, then Edge), reporting missing capability precisely, leaner process guidance, the parallel dev server memory check, and condensed memory-budget wording. No product, clinical or runtime behaviour changes.
Checks: generated from a clean worktree of origin/main. Local docs-link and inventory checks pass; the full docs-maintenance check could not run locally (a formatting dependency was missing in the temporary worktree; it fails identically without this change), so CI is the authority.
Note for local checkouts: the main checkout carries an older uncommitted copy of these two files from an earlier sync. Once this merges, those two local changes are superseded and can be discarded before pulling.
