feat(skills): brag and brag-slim join the optional-skills catalog as upstream stubs

latent-spaces/brag (MIT) turns the project you just built into a short
launch video with music, motion and share copy. It ships two skills:
/brag, the Hyperframes workflow with a bundled music and SFX library,
and /brag-slim, a single SKILL.md where the model builds the whole video
with local tools. /brag hands off to its bundled copy of brag-slim on
Claude Opus 5.5.

Both follow the impeccable/archify pattern: catalog stubs whose
metadata.hermes.upstream pointer makes
`hermes skills install official/creative/<name>` pull the live tree
through OptionalSkillSource._fetch_from_upstream. Nothing is vendored.

The brag stub documents that its Hyperframes path loads HeyGen's
hyperframes-* domain skills by name, and that the skills guard blocks
four of the five today (hyperframes-creative scores dangerous).
brag-slim has no such dependency.

Docs: two generated pages, two catalog rows, two sidebar lines.

+
+`/brag-slim` is the lean `/brag`, written for Claude Opus 5.5: no Hyperframes,
+no bundled assets. The model builds the whole launch video itself (story,
+visuals, music, sound effects, mix and render) with the tools already on the
+machine. It takes the current project directory or a website URL, reuses the
+source's real UI, fonts and assets instead of redrawing them, and writes
+`brag-output/` with the plan, the rendered video and share copy. Options:
+`--tone`, `--format landscape|vertical|square`, `--duration`.
+
+`brag` adds the classic Hyperframes workflow, the bundled soundtrack and SFX,
+and `--voice` narration (see its prerequisites). It includes this skill and
+hands off to it on Opus 5.5.
+
+## Prerequisites
+
+- No fixed toolchain: the model builds with whatever is installed. In practice
+  that means FFmpeg for the audio mix and encode, plus a headless browser
+  (Node with Playwright or Puppeteer, or Chrome) to draw frames from HTML and
+  to capture websites that render their page with JavaScript.

+tone (`default`, `polished`, `yc-parody`, `chaotic`, `deadpan`, `cinematic`,
+`app-store`, or freeform direction), storyboards a 15–25 second video, hands a
+composition brief to Hyperframes, and renders `brag-output/brag.mp4` with a
+best-frame poster and share copy. Options: `--tone`, `--format
+landscape|vertical|square`, `--duration`, `--title`, `--no-music`, `--no-sfx`,
+and `--voice` (Kokoro narration, off by default).
+
+On Claude Opus 5.5 it hands off to its bundled copy of `brag-slim` unless the
+invocation asks for `--full` or `--voice`.
+
+## Prerequisites
+
+- Node.js 22+, FFmpeg on `PATH`, and the Hyperframes CLI (`npx hyperframes
+  doctor` confirms the environment).
+- The Hyperframes path (`--full`, `--voice`, or any model other than Opus 5.5)
+  loads HeyGen's domain skills by name: `hyperframes-core`,
+  `hyperframes-animation`, `hyperframes-creative`, `hyperframes-keyframes` and
+  `hyperframes-cli`, installed with `hermes skills install
+  heygen-com/hyperframes/skills/<name>`. The skills guard currently blocks four
+  of the five on HTML comments and credential docs in their examples
+  (`hyperframes-creative` scores dangerous, which `--force` cannot override),
+  so that path is not fully installable yet. `brag-slim` has no such
+  dependency. The optional `hyperframes` skill in this catalog is a
+  single-file port and does not provide those names.
+- `uv` runs `scripts/analyze_music_cues.py` when a custom track needs beat-sync
+  cues; the bundled tracks ship precomputed cues.
+- Installs pull ~290 files (~16 MB, mostly the bundled music and SFX) through
+  the GitHub contents API. Set `GITHUB_TOKEN` or sign in with the `gh` CLI
+  first; the anonymous limit of 60 requests an hour is too low for this bundle.
