Kayos 46201c731f Phase 1 — Foundation
Mirror NPE's dependency-free spine in Rust:

* exceptions   — NetworkError + ParsingError + ContentUnavailable
                 + ExtractionError tree, with reqwest/serde_json conversions
* localization — Localization + ContentCountry, default (en, GB)
* downloader/  — Downloader trait, Request builder, Response,
                 reqwest blocking default impl
* page         — continuation-token carrier
* image        — Image + ImageSet + ResolutionLevel
                 (HEIGHT_UNKNOWN/WIDTH_UNKNOWN = -1)
* metainfo     — title/content/url/url_text grab-bag
* service      — StreamingService trait + LinkType + ServiceInfo
* newpipe      — process-global Downloader / Localization /
                 ContentCountry singleton

Foundational invariants nailed down (per SPEC §3):
* HTTP non-2xx returns Ok(Response); only 429 throws NetworkError::Recaptcha
* Response header keys lowercase-normalized
* Request.add_header PARITY with NPE bug (silent overwrite);
  append_header is our clean addition
* default Localization is en-GB
* No cookie jar in the default downloader

Tests: 7 unit + 7 live smoke against httpbin.org (gated on
'online-tests' feature). All green.

// NewPipe singleton — mirrors NPE NewPipe.java.
//
// Holds the process-global Downloader + preferred Localization +
// preferred ContentCountry. init() once at startup, then call sites read
// the globals through these getters.
//
// Concrete service registration lands in Phase 3+ once YoutubeService
// exists. Phase 1 only wires the globals.
