bump VERSION to 0.2.1

The original featured.json had 5 entries pointing at the wrong podcasts
because verification only checked the feed's <title> loosely matched.
Each wrong URL happened to share a slug/name with the intended show:

  - All-In Podcast: feeds.transistor.fm/all-in was a Verizon internal
    comms show (6 eps from 2020), not the Chamath/Sacks/Friedberg/
    Calacanis show. -> allinchamathjason.libsyn.com/rss (405 eps)
  - Code Switch: NPR feed ID 510352 was 'I\'ll Be Seeing You'.
    -> 510312 (correct Code Switch feed, 637 eps)
  - Stuff You Should Know: rss.art19.com/stuff-you-should-know was a
    different show by 'Podgo' (7 eps). -> iHeart omnycontent URL
    (2855 eps, Josh Clark & Chuck Bryant)
  - Philosophize This!: feed.podbean.com/... returned 0 items.
    -> philosophizethis.libsyn.com/rss (189 eps, Stephen West)
  - Very Bad Wizards: feed.podbean.com/... returned 0 items.
    -> feeds.libsyn.com/474285/rss (345 eps, official feed)

Bumps version 1 -> 2 so the discover store re-fetches immediately.
All 5 corrected URLs verified: 200 OK, valid RSS, matching <title>
and <itunes:author>, sensible episode counts, recent pubDates.

+# Contributing to PodTui
+
+This file is written **for humans**. If you're an AI agent or LLM working in
+this repo, read [AGENTS.md](AGENTS.md) instead — it has the machine-oriented
+build/test/lint contract and code-style rules. Both describe the same project;
+CONTRIBUTING.md focuses on *understanding* and *navigating* the codebase.
+
+PodTui is a keyboard-first, yazi-style terminal podcast client. TypeScript +
+[OpenTUI](https://github.com/opentui/opentui) on top, [Bun](https://bun.sh)
+as the runtime and toolchain.
+
+---
+
+## Quick start
+
+```bash
+brew install bun          # or: curl -fsSL https://bun.sh/install | bash
+git clone git@github.com:mikefreno/podtui.git
+cd podtui
+
+bun install               # install JS dependencies
+make native               # build libcavacore.dylib from the vendored C source
+bun run dev               # launch with hot reload (alias: make dev)
+```
+
+The app is a TUI — it expects a real terminal (Ghostty, kitty, iTerm2,
+      WezTerm, tmux, …). It will not render in a plain captured `bash` session.

+
+## Native libraries: how the FFI layer works
+
+PodTui loads **two** native libraries at runtime:
+
+1. **libopentui** — the OpenTUI renderer (shipped inside the
+   `@opentui/core-<platform>-<arch>` npm packages, copied to `dist/` by
+   `build.ts`).
+2. **libcavacore** — the audio spectrum renderer, built from C. The source is
+   vendored under `cava/` (it must stay committed — every CI runner builds it).
+   `libfftw3` is needed to build it:
+   - macOS: `brew install fftw`
+   - Debian/Ubuntu: `apt-get install libfftw3-dev`
+   (CI installs it for you; locally run `make native`.)
+
+**Critical sibling rule**: both libraries are loaded *relative to the binary*,
+so `podtui`, `libopentui.*` and `libcavacore.*` must sit in the **same
+directory**. Never move a single binary out of the tarball. The Homebrew
+formula keeps all three in `libexec/` and exposes only a `podtui` symlink.
+
+Cavacore smoke test: `bun tests/cavacore-smoke.ts`
+(FFI-calls `cava_init` / `cava_execute` / `cava_destroy` and prints results).
+
+## Gotchas (read before touching anything)
+
+1. **Never add a top-level `preload` to `bunfig.toml`.**
+   A compiled PodTui binary's embedded runtime reads the *launching process's*
+   CWD `bunfig.toml`, and a `preload` entry points at a module the standalone
+   can't resolve (`@opentui/solid/preload`) → the binary dies at startup with
+   `preload not found`. This is why `bunfig.toml` has **no** top-level
+   `preload`; dev-mode preloading happens via explicit `--preload` flags in
+   `package.json`. The `[test]` section *does* keep a preload — that only
+   affects `bun test`.
+
+2. **Smoke-test the compiled binary from a bunfig-free dir.**
+   Because of (1), `./dist/podtui --version` run from the repo root launched
+   inside CI would fail. CI always unpacks the tarball into a `mktemp` dir
+   before booting. Do the same when testing a release build locally.
+
+3. **Homebrew's dylib-repair warning is benign.**
+   `brew install` may print “load commands do not fit in the header … needs
+   `-headerpad`” for a prebuilt dylib. The app dlopens the libs by path, so
+   the warning is cosmetic; installs complete and the app boots.
+
+## Testing
+
+```bash
+bun test                # full suite   (54 tests across 6 files today)
+```
+
+The suite covers the keyboard/nav model, keybind dispatch, and the yazi pane
+logic; plus `tests/cavacore-smoke.ts` asserting the native lib exports.
+
+For scripted end-to-end interaction there's a **headless harness**,
+`scripts/tui-harness.tsx`: each invocation snapshot-rebuilds the app state
+into a sandboxed `.harness/` config dir, replays the saved action log
+(`.harness/actions.json`), executes one more key/action passed on the CLI, and
+prints the resulting frame + a style summary — all without a real terminal.
+Audio is a no-op during those snapshots. The last frame lands in
+`.harness/last-frame.{json,txt}` for inspection.
+
+## Releasing
+
+Releases are built and published from **tags**
+
+### Steps
+
+1. Run `scripts/release-tag.sh` (interactive: pick major/minor/patch/custom,
+   confirms the plan, bumps `VERSION` in `src/index.tsx`, commits, tags
+   `vX.Y.Z`, and pushes branch + tag to every remote). If the version bump is
+   already committed but the tag is missing, it offers a tag-only path.
+   `--dry-run` prints the plan without doing anything.
+2. Equivalent manual commands:
+
+   ```bash
+   git tag -a v0.2.0 -m 'PodTUI v0.2.0' && git push gh v0.2.0
+   ```
+
+3. CI (`.github/workflows/release.yml`) runs four builds in parallel,
+   each producing `podtui-<platform>-<arch>.tar.gz`:
+
+   | Runner              | Platform/Arch |
+   |---------------------|---------------|
+   | `ubuntu-latest`     | linux-x64     |
+   | `ubuntu-24.04-arm`  | linux-arm64   |
+   | `macos-15-intel`    | darwin-x64    |
+   | `macos-14`          | darwin-arm64  |
+
+   Each runner: installs deps → installs fftw → `scripts/build-cavacore.sh`
+   → `make dist` → smoke-boots the binary from a temp dir → uploads the
+   tarball. (`macos-15-intel` matters: GitHub's `macos-latest` is arm64 now.)
+
+4. A release is auto-created with all 4 tarballs attached. `brew` never
+   sees the new version: the **tap self-updates**: the
+   `mikefreno/homebrew-podtui` repo has a scheduled workflow (hourly) that
+   polls GitHub releases, and when a new tag appears, rewrites
+   `Formula/podtui.rb` (URLs + arm64/x64 `sha256`) and pushes it — no
+   secrets. See `scripts/sync-formula.sh` in that repo for the logic. Local
+   test: `brew install mikefreno/podtui/podtui`.
+5. **AUR packaging** (`packaging/aur/PKGBUILD`): the `podtui-bin` package is
+   staged, not yet published (AUR account registrations are closed; see the
+   README note in section 3). On each release, keep the AUR sources in sync
+   with the new tag: bump `pkgver`, recompute the two tarball `sha256sums`
+   entries, keep the `LICENSE` asset source (the workflow above uploads
+   `LICENSE` to every release), and regenerate `packaging/aur/.SRCINFO` with
+   `bash packaging/aur/gen-srcinfo.sh`.
+
+### Manual fallback
+
+If you ever need to sync the tap by hand (or before the hourly job runs):
+
+```bash
+cd <clone of mikefreno/homebrew-podtui>
+./scripts/sync-formula.sh 0.2.0
+git commit -am 'podtui 0.2.0' && git push
+```
+
+### Local release build
+
+```bash
+make dist          # builds the binary + tarball for THIS machine only
+```
+
+Bun cannot cross-compile — the other platforms come from CI.
+
+---
+
+## Open items / things to sort out
+
+- **LICENSE**: `README.md` says "TBD — choose and document a license before
+  the first release". Pick one (MIT/BSD-3) and add `LICENSE` + update the
+  README footer.
+- **Native libs in `dist/` still need committing?** No — they're built from
+  sources kept in the repo (`cava/`, `node_modules/@opentui/core-*`). Only
+  `src/native/libcavacore.dylib` is a committed binary artifact; macOS arm64
+  ships from it directly until a full rebuild replaces it. On other hosts the
+  `make native` build is required — see `scripts/build-cavacore.sh`.
