enricobuehler	12843fe253	feat(protocol,clients): codec preference negotiation + Linux client decodes per Welcome (Phase 2a) ... Adds a client-selectable **preferred codec** and wires the core + ABI + probe + Linux client to negotiate and decode it. (Windows/Apple/Android follow in 2b.) **Core:** - `Hello.preferred_codec` (a single CODEC_* bit, 0 = auto) — a soft hint appended after `video_codecs`. `resolve_codec(client, host, preferred)` now honors the preference when the host can also emit it, else falls back to precedence (HEVC > AV1 > H.264). Roundtrip + preference tests. - `NativeClient::connect` takes `video_codecs` + `preferred_codec`; `NativeClient.codec` exposes the resolved `Welcome.codec`. - ABI: `punktfunk_connect_ex7` (adds the two codec params; `ex6` delegates to it advertising HEVC-only) + `punktfunk_connection_codec` getter + `PUNKTFUNK_CODEC_{H264,HEVC,AV1}` constants (drift-guarded against the wire values). Header regenerated. **Host:** passes `hello.preferred_codec` into `resolve_codec`. **probe:** `--codec h264|hevc|av1|auto` sets the preference (still advertises it can decode all three); the dump extension already follows the resolved codec. **Linux client:** advertises the codecs FFmpeg can actually decode (`decodable_codecs()`), threads the user's `codec` setting as the preference, and builds the decoder — both the software and VAAPI paths, plus the mid-session VAAPI→software demotion — from the negotiated `Welcome.codec` instead of hardcoding HEVC. New "Video codec" dropdown in Preferences (Automatic/HEVC/H.264/AV1). Live-validated on the dev box: probe `--codec hevc` against a software (H.264-only) host resolves to H.264 (graceful soft-preference fallback), no failure. clippy + core (57) + host (133) tests green.

enricobuehler	d6596ff81b	docs: rework client/crate READMEs, add missing ones ... Rework the client READMEs to be accurate and inviting to first-time visitors, and fill in the gaps where crates and tools had none. - Rewrite clients/{apple,android,decky} READMEs (features-first, trim dense internal narrative; drop the stale "one session at a time" / "renegotiation not implemented" section from the Apple README). - Add READMEs for clients/{linux,windows,probe}, which had none. - Add crate READMEs for punktfunk-host, punktfunk-core, pf-driver-proto. - Add brief READMEs for tools/{loss-harness,latency-probe}. - Fix packaging/README duplicate "Option B" heading (bootc -> Option C). - Fix docs-site/README stale docs/ -> design/ reference. - De-stale packaging/windows/drivers/pf-dualsense README (drop "M0 spike" / external-checkout framing; reflect in-tree workspace + shipped + installer-bundled + multi-pad), keeping the driver-authoring lore.
