Key validation through GET /v1/models; usage has no public REST endpoint so the snapshot reports reachable muse-spark models only. Cost stays unknown, never synthesized. Closes nesszer#478

Provider identity is now Meta (company) with cli_name 'meta' and display name 'Meta'. Model IDs stay muse-spark-* (muse-spark-1.3 default). Backwards compat: 'metaspark', 'meta-spark', 'muse-spark', 'musespark', 'meta muse spark' CLI aliases, serde alias, legacy 'codexbar-metaspark' keyring target and METASPARK_API_URL env override still resolve.

- Line 168: Update the MetaSpark primary window construction near
RateWindow::with_details so the quota-less 0.0 placeholder is marked
informational, preferably by using RateWindow::informational(note) or setting
primary.is_informational to true while preserving the existing note.
- Line 18: Update METASPARK_API_BASE so resolving "models" with join preserves
the /v1 path, and add a regression test covering the resulting default URL.

docs.rs reqwest Url join relative URL path trailing slash url crate
💡 Result:
In Rust, the reqwest crate relies on the url crate for URL manipulation [1][2]. The join method behaves specifically based on whether the base URL has a trailing slash [1][3]. Key Behavior of.join: A trailing slash in the base URL is significant [1][2]. - If the base URL ends with a trailing slash (e.g., https://example.net/a/b/), the joined path is appended as a new segment (e.g., https://example.net/a/b/c.png) [1][3]. - If the base URL does not have a trailing slash (e.g., https://example.net/a/b.html), the last path component is treated as a file name and is removed/replaced by the joined path (e.g., https://example.net/a/c.png) [1][2]. Important Considerations: - Leading Slashes: If the input string to join starts with a forward slash (/), it is treated as an absolute path relative to the domain root, replacing the entire existing path of the base URL, regardless of whether the base URL has a trailing slash [2][4]. To avoid this behavior, ensure the input string does not start with a slash [5][6]. - Alternative Approaches: If you wish to append segments to a URL without worrying about the trailing slash of the base URL, consider using the path_segments_mut API [7][4]. This allows you to safely push segments onto the path [6]: let mut url = Url::parse("https://example.com/base")?; url.path_segments_mut.map_err(|_| "cannot-be-base")?.push("new_segment"); // Result: https://example.com/base/new_segment For more complex scenarios where you need to guarantee a base URL acts as a directory, developers often ensure the URL ends with a slash before using join [6].

Preserve the /v1 path when resolving models.
probe_models calls join("models") on METASPARK_API_BASE. Because the base URL has no trailing slash, the request becomes https://api.meta.ai/models instead of https://api.meta.ai/v1/models.

Closes #478.
Summary
Adds Meta Muse Spark (muse-spark-1.3 family) as a Win-CodexBar provider, following the same pattern as existing API-key providers.
Meta's Model API (https://api.meta.ai/v1) exposes no public billing/usage REST endpoint (usage lives in the dashboard), so this is key-validation-only: Bearer MODEL_API_KEY (alias META_API_KEY) against GET /v1/models. 401/403 maps to auth-required; reachable muse-spark-* model ids ride the primary window note at 0%. Cost stays absent (unknown, never $0).
