release(v4.5.0): browser-side encrypted storage + multi-factor unlock

Adds the foundations Prism's web client (and any future browser-based
Shade app) needs: at-rest-encrypted IndexedDB storage that mirrors the
SQLite backend byte-for-byte at the AAD/nonce level, browser-safe
subpath imports so Vite/webpack/esbuild stop hitting bun:sqlite, and
KeyManager support for argon2id and N-factor composite unlock.

@shade/storage-encrypted
- EncryptedIndexedDBStorage (subpath: /idb) — full StorageProvider
  using one object store per _enc table; reuses aeadSeal/aeadOpen +
  row-codec sealers so a row sealed under the SQLite or Postgres
  backend decrypts under IDB given the same KeyManager.
  bumpPeerIdentityVersion is atomic under one IDB transaction.
- KeyManager argon2id source — memory-hard KDF for low-entropy
  secrets (PINs). Backed by @noble/hashes/argon2 (already a transitive
  dep). DEFAULT_ARGON2ID exported (m=64 MiB, t=3, p=1).
- KeyManager composite source — HKDF-combine N sub-sources into one
  master. Every source mandatory; order significant by design;
  composite-of-composite rejected; optional info string for app-level
  domain separation.
- Subpath exports (/crypto, /sqlite, /postgres, /idb) plus a `browser`
  condition on the default import that resolves to a barrel
  excluding the Bun- and Postgres-specific entries. Browser bundles
  no longer pull bun:sqlite transitively.

Tests
- 73 tests in shade-storage-encrypted (was 31). New coverage:
  argon2id determinism + reject paths, composite same-factors → same
  master, wrong-PIN/passphrase/order-swap → different master, info
  domain separation, all 28 StorageProvider methods on
  EncryptedIndexedDBStorage, fingerprint-mismatch rejection, and
  cross-impl roundtrip with EncryptedSQLiteStorage proving the AAD/
  nonce derivation is implementation-agnostic.

## [4.5.0] — 2026-05-07 — Browser-side encrypted storage + multi-factor unlock
Browser-based Shade clients (Prism's web client being the first) needed
the same at-rest encryption story as the desktop SQLite path: identity,
prekeys, sessions and stream-resume state persisted across reloads,
unwrapped from a user-supplied passphrase — and on browsers, optionally
gated behind a second factor (PIN) since there is no OS-session boundary
to lean on. The existing barrel of `@shade/storage-encrypted` also
transitively imported `bun:sqlite` and `postgres`, which prevented Vite/
webpack/esbuild from producing a clean browser bundle.
This release adds an encrypted IndexedDB backend that mirrors
`EncryptedSQLiteStorage` byte-for-byte at the AAD/nonce level, exposes
browser-safe subpath imports, and lets `KeyManager` derive its master
key from low-entropy secrets (argon2id) and from N composed factors
(every factor mandatory).
### Added
#### `@shade/storage-encrypted`
- `EncryptedIndexedDBStorage` — IndexedDB-backed `StorageProvider`
exposed via `@shade/storage-encrypted/idb`. One object store per
`_enc` table from the SQLite schema, sealed payloads as `Uint8Array`,
routing/timestamp fields kept plaintext for query efficiency. Reuses
`aeadSeal`/`aeadOpen` and the `row-codec` sealers verbatim — a row
sealed under the SQLite or Postgres backend decrypts under IDB given
the same `KeyManager`. `bumpPeerIdentityVersion` is atomic under one
IDB transaction (closes the read-then-upsert race the SQLite version
has).
- `KeyManager.open({ kind: 'argon2id', ... })` — memory-hard KDF for
low-entropy secrets (PINs, short passwords). Backed by
`@noble/hashes/argon2` (already a transitive dep — pure JS, browser
safe). `DEFAULT_ARGON2ID` exported (m=64 MiB, t=3, p=1, 32-byte
output; ~250400 ms in modern browsers).
- `KeyManager.open({ kind: 'composite', sources, info? })`
HKDF-combine N sub-sources into one master key. Every source is
required: omitting or substituting any source yields a different
master key and `open()` fails on the storage-key-fingerprint check.
Order is significant by design (`[pwd, pin]``[pin, pwd]`).
Composite-of-composite is rejected.
- Subpath exports: `@shade/storage-encrypted/crypto` (KeyManager + KDF
+ AEAD + row-codec, no SQLite/Postgres bindings), `/sqlite` (Bun),
`/postgres` (Node), `/idb` (browser). The `browser` condition on the
default import resolves to a barrel that excludes Bun/Postgres
imports — `import { KeyManager } from '@shade/storage-encrypted'` now
bundles cleanly under Vite without hitting `bun:sqlite` resolution
errors.
- Dependency: `idb` ^8.0.3.
### Tests
- `packages/shade-storage-encrypted/tests/key-manager-multi-factor.test.ts`
— argon2id determinism + reject paths, composite same-factors → same
master, wrong-PIN/wrong-passphrase/order-swap → different master,
explicit `info` domain separation, nested-composite rejection.
- `packages/shade-storage-encrypted/tests/encrypted-indexeddb.test.ts`
— full round-trip coverage of all 28 `StorageProvider` methods,
fingerprint-mismatch rejection on wrong key, atomic peer-identity
bump, plus cross-impl roundtrip with `EncryptedSQLiteStorage`
proving the AAD/nonce derivation is implementation-agnostic.
