Found while running the lutris plugin's own release gate against a live host on
.21: `parity --compare` reported `1 missing` — the plugin produced NO entry for
the one game Lutris had, while the host's built-in scanner produced it fine.
`scan` agreed: "present: 0 games". `detect` still said "present", because detect
only stats the file.

`openReadOnly` builds a `file:<path>?immutable=1` URI — the right idea, since
`immutable=1` is what makes this a pure read that cannot lock a running
launcher's database or spawn WAL sidecars next to it. But it opened that name
with `{ readonly: true }`, and the options object does NOT enable SQLite's URI
filename parsing. Without SQLITE_OPEN_URI the name is taken literally, no such
file exists, and the open throws:

    SQLiteError: unable to open database file

Every path here then degrades that to silence by design: `openReadOnly` returns
`undefined` for "this launcher isn't installed", `withReadOnlyDb` passes the
`undefined` through, and callers write `withReadOnlyDb(...) ?? []`. So a total,
permanent failure to read ANY database was indistinguishable from an empty
library. The lutris plugin reported 0 games on every Linux box, always.

It is platform-split, which is why it survived review and local runs: macOS
links Apple's system SQLite, which is built with URI filenames enabled, so the
same call succeeds there. Linux uses Bun's bundled SQLite, which is not. MEASURED
both ways on bun 1.3.14.

Fixed by passing the flags explicitly — SQLITE_OPEN_READONLY | SQLITE_OPEN_URI.
(`{ readonly: true, uri: true }` is not a supported option shape; also measured.)

And the second half, which is why nothing caught it: `parity --compare` sets
`process.exitCode = 1` on a mismatch and then returns NORMALLY — a red parity is
a finished comparison, not a crashed command. `runPluginCli` then assigned
`process.exitCode = 0` unconditionally after the effect resolved, overwriting it.
So the one verb both plugin READMEs document as the release gate — "exits
non-zero on any difference", "do not publish a version whose parity run is red" —
always exited 0, and any scripted use of it passed. Now `??= 0`, so a code a
command set deliberately survives.

Tests: the sqlite helper had NO coverage at all, which is the whole reason a
total failure shipped looking like an empty library. Added five cases against a
REAL database file — reads rows back, handles a path needing URI escaping,
withReadOnlyDb round-trips, an absent file is `undefined` not a throw, and a bad
query still degrades to []. Verified they actually catch it: against the shipped
code on Linux, 4 of the 5 fail; with the fix, 21/21 in that file and 61/61 across
the suite, typecheck and build clean.

End to end on .21 with the fix: lutris `scan` goes 0 -> 1 games and
`parity --compare` reports "parity OK — 1 entries identical". A deliberately
doctored baseline now exits 1 instead of 0.

0.3.0 -> 0.3.1.

The ~80% of every plugin that was copy-pasted (rom-manager ↔ playnite),
extracted as one Effect-v4 package:

- runtime: definePluginKit — async-main boundary hiding a ManagedRuntime
  (two-effect-instances discipline), signal-driven interruption with a
  bounded shutdown grace
- config: Schema-driven raw round-trip (defaults only in the Schema via
  withDecodingDefaultKey + encodingStrategy omit; file stays authored-shape),
  atomic writes, world-writable refusal, changes stream
- cache-store: disposable derived state, corrupt→empty, write-through
- reconcile: kit-owned provider wire schemas + typed client over the
  skew-safe untyped pf.request seam
- sync-engine: generic poll/watch/debounce/single-flight-coalesce/
  fingerprint-skip engine with a status PubSub (the SSE feed)
- ui-server + sse: effect/unstable/httpapi behind servePluginUi with
  core-only env layers (validated by the phase-0 spikes); raw SSE route
  (httpapi has no event-stream media type)
- cli: minimal command dispatcher reusing the plugin layer graph
  (deliberately not effect/unstable/cli — it needs platform packages)
- react subpath: plugin router (path→hash→fallback deep-link restore +
  pf-ui:navigate bridge), ResultGate, sseAtom, resolvePluginBase
- theme.css: the console's violet identity packaged for plugin UIs

18 bun tests incl. the two phase-0 spikes; publish workflow mirrors
sdk-publish (tag plugin-kit-v*; 0.1.0 published manually).
