2.1.0 — quick-wins train: brief load, offline-durable capture, session-end verb

Three independently useful changes (IMPROVEMENT-PLANS #1/#3/#7), no schema changes:

- load --brief: token-budgeted cold-start digest (facts full, last-10 observations,
  scope+freshness, last session's key sections, agent-log lines, inbox count;
  ECHO_LOAD_BUDGET ~8000 chars, lowest-priority-first trimming). SessionStart hook
  injects the brief form; /echo-load keeps the full dump. All load reads (+ the
  sessions listing, which also feeds the heartbeat fallback) fetched in parallel.
- Offline capture durability: a fully-offline capture queues the WHOLE op as one
  semantic record; flush replays it through capture so routing/gate/aliasing re-run
  against the current index; a gate stop on replay is kept + flagged
  (needs_attention, surfaced by flush and load), never landed blind; update-path
  and ensure_daily_log writes ride safe_request; same-args captures dedupe.
- session-end: one call, one lock — session log -> agent-log line -> reflect
  proposals (gate-aware) -> optional scope set -> heartbeat LAST as the commit
  marker; dry-run default; ECHO_NOW pins HHMM; validation runs before any write.
  Stop hook nudge names the command and recognizes it as reflected.
- Fix: main() now catches the __main__ twin-module EchoError (via RuntimeError +
  .code) so helper-module errors exit with their intended codes, not tracebacks.

+19 e2e checks; all suites green. Plans renumbered: MCP container is 2.2.
