ZacharyZhang-NY e74dafcd36 Silence render-disposed spam, unbreak bundled skills, drop board wake
Three independently ugly bugs that all fed the same log flood:

* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
  to stderr via `console.error`. When the worker fans a second
  agent-event past a reloading renderer, we produced thousands of
  identical lines and stalled the main loop on stderr I/O. Added a
  `mainFrame.detached` guard so the send is short-circuited before
  Electron's own catch block fires, and installed a targeted filter in
  `suppress-warnings.ts` (now actually imported from the entry point)
  so the specific `console.error("Error sending from webFrameMain:"…)`
  noise never reaches the terminal. Any other payload still surfaces.

* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
  target when an agent replied to `__board__` — `wakeAgentIfPossible`
  then called `db.getAgent("__board__")`, threw, and the dispatcher
  kept repeating on every send. Strip `HUMAN_SENDER_ID` at
  `resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
  heartbeat so a stray caller (future automation fan-out) cannot
  reintroduce the crash.

* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
  diverges from its parent directory. The four bundled `my-writing-style`
  copies declared `name: writing-style-skill`, so every install emitted
  a warning and dropped the skill. They also lived as orphan gitlinks
  (mode 160000 without .gitmodules), and the global `*.md` gitignore
  hid every other SKILL.md from version control. Fixed the frontmatter
  to match the dir, converted the dangling submodules to plain trees,
  and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
  catalogue instead of silently losing it.

# Sections
This file defines all sections, their ordering, impact levels, and descriptions.
The section ID (in parentheses) is the filename prefix used to group rules.
---
## 1. Meaningful Names (name)
**Impact:** CRITICAL
**Description:** Names are the primary documentation. Bad names cascade confusion throughout the codebase, forcing every reader to decipher intent.
## 2. Functions (func)
**Impact:** CRITICAL
**Description:** Functions are the verbs of code. Small, focused functions enable understanding, testing, and reuse while reducing complexity.
## 3. Comments (cmt)
**Impact:** HIGH
**Description:** Comments should explain intent, not obvious mechanics. Wrong or stale comments actively mislead readers and cost more than no comments.
## 4. Formatting (fmt)
**Impact:** HIGH
**Description:** Consistent formatting reduces cognitive load. Code should read top-to-bottom like a newspaper article.
## 5. Error Handling (err)
**Impact:** HIGH
**Description:** Clean error handling separates happy path from exceptional cases. Use the error mechanism idiomatic to your language (exceptions, Result types, or explicit error returns).
## 6. Objects and Data Structures (obj)
**Impact:** MEDIUM-HIGH
**Description:** Objects hide data and expose behavior; data structures expose data and have no behavior. Mixing these creates hybrid messes.
## 7. Boundaries (bound)
**Impact:** MEDIUM-HIGH
**Description:** Third-party code and external APIs are boundaries. Wrap them to isolate change, ease testing, and maintain control over your codebase's interfaces.
## 8. Classes and Systems (class)
**Impact:** MEDIUM-HIGH
**Description:** Classes should be small and have a single responsibility. Systems should separate construction from use. SRP and DIP are among the highest-leverage design principles.
## 9. Unit Tests (test)
**Impact:** MEDIUM
**Description:** Tests are first-class citizens that enable safe refactoring. Test code deserves the same care as production code.
## 10. Emergence and Simple Design (emerge)
**Impact:** MEDIUM
**Description:** Good design emerges from following four rules in order: pass tests, reveal intent, eliminate duplication, minimize elements. Resist the urge to over-engineer.
