v0.0.3

Release v0.0.3 (#16)

Patch release **v0.0.3**, cut from current `main` per
[RELEASING.md](RELEASING.md).

## What ships since v0.0.2
- #15 — Add `face` verb + collection lifecycle, backed by tinycloud ≥
0.3.4

## This PR
Version-only bump. `npm version 0.0.3 --no-git-tag-version` +
`scripts/sync-version.mjs` propagated `0.0.3` to all four surfaces:
- `package.json` / `package-lock.json`
- `src/version.ts` (`OVERCAST_VERSION`)
- `.claude-plugin/plugin.json`
- `.claude-plugin/marketplace.json` (`metadata.version` +
`plugins[].version`)

`node scripts/sync-version.mjs --check` ✅ all surfaces match.

## After merge
Tag `main` to trigger `release.yml` (npm OIDC publish + bun binaries):
```
git checkout main && git pull
git tag v0.0.3 && git push origin v0.0.3
```

> **Low Risk**
> Mechanical version string updates only; no logic, API, or dependency
changes in the diff.
> 
> **Overview**
> **Release v0.0.3** — version-only bump from **0.0.2** to **0.0.3**
across every published version surface, with no application or
dependency changes in this diff.
> 
> `package.json` and `package-lock.json` are updated for npm;
**`OVERCAST_VERSION`** in `src/version.ts` drives CLI `--version` and
TUI branding; **`.claude-plugin/plugin.json`** and
**`.claude-plugin/marketplace.json`** (metadata + plugin entry) stay
aligned for the Claude plugin marketplace. Functional work for this
release (e.g. the `face` verb from #15) is already on `main`; this PR
only cuts the release label.
