chore(agents): add CEO daily notes and rewrite founding-engineer/plan-reviewer configs

CEO memory notes for 2026-03-11 and 2026-03-12 capture the full timeline of
GIT-2 (founding engineer evaluation), GIT-3 (calibration task), and GIT-6
(plan reviewer hire).

Founding Engineer: AGENTS.md rewritten from 25-line boilerplate to 3-layer
progressive disclosure model (AGENTS.md core -> DOMAIN.md reference ->
SOUL.md persona). Adds HEARTBEAT.md checklist, TOOLS.md placeholder. Key
changes: memory system reference, async runtime warning, schema gotchas,
UTF-8 boundary safety, search import privacy.

Plan Reviewer: new agent created with AGENTS.md (review workflow, severity
levels, codebase context), HEARTBEAT.md, SOUL.md. Reviews implementation
plans in Paperclip issues before code is written.

+# 2026-03-12 -- CEO Daily Notes
+
+## Timeline
+
+- **02:59** Heartbeat timer wake. No PAPERCLIP_TASK_ID, no mention context.
+- **02:59** Auth: JWT working (fish shell curl quoting issue; using Python for API calls).
+- **02:59** Inbox: 0 assignments (todo/in_progress/blocked). Dashboard: 1 open, 0 in_progress, 0 blocked, 3 done.
+- **02:59** Spend: $27.50. Clean exit -- nothing to work on.
+- **08:41** Heartbeat: assignment wake for GIT-6 (Create Plan Reviewer agent).
+- **08:42** Checked out GIT-6. Reviewed existing agent configs and adapter docs.
+- **08:44** Created `agents/plan-reviewer/` with AGENTS.md, HEARTBEAT.md, SOUL.md.
+- **08:45** Submitted hire request: PlanReviewer (codex_local / chatgpt-5.4, role=qa, reports to CEO).
+- **08:46** Approval 75c1bef4 pending. GIT-6 set to blocked awaiting board approval.
+- **09:02** Heartbeat: approval 75c1bef4 approved. PlanReviewer active (idle). Set instructions path. GIT-6 closed.
+- **10:03** Heartbeat timer wake. 0 assignments. Spend: $24.39. Clean exit.
+
+## Observations
+
+- GIT-4 (hire QA agents) still open and unassigned. Board needs to assign it or mention me.
+- Fish shell variable expansion breaks curl Authorization header. Python urllib works fine. Consider noting this in TOOLS.md.
+- PlanReviewer review workflow uses `<plan>` / `<review>` XML blocks in issue descriptions -- same pattern as Paperclip's planning convention.
+
+## Today's Plan
+
+1. ~~Await board assignments or mentions.~~
+2. ~~GIT-6: Agent files created, hire submitted. Blocked on board approval.~~
+3. ~~When approval comes: finalize agent activation, set instructions path, close GIT-6.~~
+4. Await next board assignments or mentions.
