v0.5.0 — The console grows system software

The console grows system software. Streaming media, a system keyboard, a
virtual pointer, and self-diagnosing devices — capabilities every handheld
app needs, now owned by the framework instead of copy-pasted per demo —
proven by streaming YouTube to a PSP over USB.

• App services over USB — the pocket-svc mailbox gives any app a JSON
  command channel to a companion desktop service (request/reply with side
  files for bulk bytes), the same file-transport model DevTools proved,
  hardened against host restarts. Pocket YouTube — search, host-rendered CJK
  result rows, and full-motion playback on real hardware — ships as its own
  app repo (pocket-stack/pocket-youtube) built entirely on these APIs.
• A streaming video plane — .pkst ring files carry palettized frames
  and PCM audio from the host; the native side pumps them under a per-frame
  IO budget, commits texture updates only in the GE-idle window (tear-free
  by construction), and plays audio on a dedicated hardware channel with a
  software resampler. Seek, pause, and epoch resync are part of the
  contract, not the app.
• A system on-screen keyboard — @pocketjs/framework/osk: an LVGL-style
  variable-width key grid with letters/caps/symbols layers, dark and light
  themes, and a caret-editing session (createOsk). While open it owns
  input outright (modal focus scope + button block), retiring the
  gate-every-handler pattern. One component, per-platform input: d-pad
  spatial navigation and the classic PSP chords, front-touch on Vita, and
  the virtual cursor for free.
• A virtual cursor capability (input.cursor) — the analog nub steers a
  core-drawn pointer; hover is focus, so every focus: style doubles as
  the hover style, presses arm and fire like real buttons, and d-pad
  traversal stays available as a fallback. Opt-in via enableCursor().
• Devices that vouch for themselves — every build embeds an FNV-1a64
  hash of its app bundle; the PSPLINK bridge verifies it against dist/ on
  every boot and calls out a stale embed (or a silent, pre-handshake build)
  before you trust a single observation. OP.debugStats exposes live
  audio/video/transport counters through the new DevTools devStats query —
  underruns, torn frames, and truncation resets become one request instead
  of a thread autopsy.
• Compatibility: existing apps build unchanged. New host ops (30–38) are
  optional capabilities — hosts that lack them simply omit the op, and the
  framework degrades gracefully (the OSK falls back to bottom-dock geometry
  without hit testing; devStats replies data: null). PS Vita builds now
  ship complete default LiveArea artwork.
