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.

Importing assets in Remotion

The public folder

Place assets in the public/ folder at your project root.

Using staticFile()

You MUST use staticFile() to reference files from the public/ folder:

import { Img, staticFile } from "remotion";

export const MyComposition = () => {
  return <Img src={staticFile("logo.png")} />;
};

The function returns an encoded URL that works correctly when deploying to subdirectories.

Using with components

Images:

import { Img, staticFile } from "remotion";

<Img src={staticFile("photo.png")} />;

Videos:

import { Video } from "@remotion/media";
import { staticFile } from "remotion";

<Video src={staticFile("clip.mp4")} />;

Audio:

import { Audio } from "@remotion/media";
import { staticFile } from "remotion";

<Audio src={staticFile("music.mp3")} />;

Fonts:

import { staticFile } from "remotion";

const fontFamily = new FontFace("MyFont", `url(${staticFile("font.woff2")})`);
await fontFamily.load();
document.fonts.add(fontFamily);

Remote URLs

Remote URLs can be used directly without staticFile():

<Img src="https://example.com/image.png" />
<Video src="https://remotion.media/video.mp4" />

Important notes

  • Remotion components (<Img>, <Video>, <Audio>) ensure assets are fully loaded before rendering
  • Special characters in filenames (#, ?, &) are automatically encoded
