fix: send SetPixelFormat to request 8bpp RGB332

The OmniView defaults to 16bpp when no SetPixelFormat is sent.
The Java applet sends SetPixelFormat (msg type 0) at
ByteColorRFBRenderer.new() line 76 to request 8bpp RGB332
(bpp=8, depth=8, true_color, red_max=7, green_max=7, blue_max=3,
shifts 0/3/6). Without this, pixel data arrives as 16bpp pairs
that produce green stripe artifacts when interpreted as 8bpp.
Verified: snapshot now matches the reference screenshot from
http://10.3.0.130/screenshot.jpg (dark screen with "Free" label).

framebuffer.rs:
- Framebuffer struct (8bpp RGB332, row-major)
- apply_raw() blit, copy_rect() with overlap-safe logic
- to_rgba() via compile-time RGB332 LUT
session.rs:
- ActiveSession: connect + SetEncodings + initial FBUpdateRequest
- Full server message dispatch loop (all 15 message types)
- Raw (encoding 0) and CopyRect (encoding 1) decoders
- Ping response, bandwidth probe bookends, mode change resize
examples/snapshot.rs:
- Connects, waits for first FramebufferUpdate, saves PNG
- Tested against real OmniView at 10.3.0.130:443
- Successfully captured 640x480 frame

handshake.rs:
- Config, PixelFormat, ServerInit, Session types
- connect() walks all 11 handshake steps per aw.g() line 226
- Auth error mapping from aw.a(int) line 350 (7 error codes)
msg.rs — client-to-server writers:
- SetEncodings (type 2), FramebufferUpdateRequest (type 3)
- KeyEvent (type 4), PointerEvent (type 5, 8 bytes)
- PingResponse (type 149), BandwidthMarker (type 151)
msg.rs — server message dispatch:
- ServerMsg enum covering all 15 message types
- Readers for ping, bandwidth probe, ack, debug string,
RFB command, server cut text, server name update,
layout/locale, RDP event, FB update header
examples/handshake.rs: connects and prints session info.

style: apply rustfmt to proto.rs

Fixes CI fmt check failure — rustfmt wants multi-line assert_eq! for
long struct literals and the varint roundtrip assertion.

feat: phase 0+1 — workspace scaffold and protocol primitives
...
Phase 0: Cargo workspace with ericrfb (lib) and ericrfb-proxy (bin)
crates, .envrc for RUST_LOG, workspace dependency pins.
Phase 1: ericrfb/src/proto.rs implements all wire primitives:
- read/write helpers matching h.java (u8, i8, u16-BE, i16-BE, i32-BE)
- varint reader/writer matching aw.int() (1-3 bytes, Tight lengths)
- modified-UTF-8 string reader matching h.byte()
- RectHeader { x: u16, y: u16, w: u16, h: u16, encoding: i32 }
- RGB332 → RGBA compile-time LUT (256 entries)
20 tests including proptest varint roundtrip over [0, 2^22).
