feat(sync): add kenari sync adapter

[doedja]

Adds Kenari (kenari.id) to the hourly model sync workflow so its catalog stays current automatically instead of via hand-opened PRs.

How it works

• Fetches the public https://kenari.id/v1/models endpoint. No API key and no repo secret needed.
• Cost stays 0 by policy: Kenari bills in IDR from a prepaid wallet at its own catalog prices, so USD figures here would be a misleading currency conversion. The zero cost matches every existing hand-authored providers/kenari entry.
• Existing factored TOMLs are preserved exactly as authored. Limits keep inheriting the canonical base model.
• New models sync only when a canonical models/ metadata entry exists to inherit capability facts from (factorBaseModel). Kenari's dash IDs resolve to the dotted canon generically (grok-4-5 -> xai/grok-4.5), no per-model alias table.
• Models with no canonical entry are skipped and surfaced in the sync-report notice (currently hy3:free) rather than authored from API data that has no name/release-date fields.
• Reasoning effort values come verbatim from the endpoint's reasoning_options array (per-model, e.g. "reasoning_options":["low","medium","high","xhigh","max"] on claude-fable-5). A model with "reasoning": true and no advertised efforts gets reasoning_options = [], matching the existing hand-authored entries.

Reasoning effort values advertised by the endpoint

Model	/v1/models reasoning_options
claude-fable-5, claude-sonnet-5	["low","medium","high","xhigh","max"]
gpt-5-6-luna, gpt-5-6-sol, gpt-5-6-terra	["none","low","medium","high","xhigh","max"]
grok-4-5	["low","medium","high"]
mimo-v2-5:free	none advertised (reasoning: true) -> reasoning_options = []

First sync (included in this PR)

Status	Models
Created (7)	claude-fable-5, claude-sonnet-5, gpt-5-6-luna, gpt-5-6-sol, gpt-5-6-terra, grok-4-5, mimo-v2-5:free
Deleted (1)	deepseek-v4-pro:free (no longer served)
Unchanged	22 (byte-identical)

Verification

• bun models:sync kenari twice: second run is a no-op (0 created, 0 updated, 0 deleted)
• bun validate passes
• bun run test: same 3 pre-existing failures as a clean checkout of dev, none related

Action items

• [low] [violation] providers/kenari/models/claude-fable-5.toml:5 (also claude-sonnet-5.toml, gpt-5-6-luna.toml/sol/terra, grok-4-5.toml) - Check: The audit-reasoning-options skill requires explicit provider evidence for non-standard effort values (none, xhigh, max), and PR-body citations must state what each source proves. Why: The PR body cites the https://kenari.id/v1/models endpoint but never mentions reasoning_options at all, while the new files assert provider-specific effort sets like ["low","medium","high","xhigh","max"] (Claude 5), ["none","low","medium","high","xhigh","max"] (GPT-5.6), and ["low","medium","high"] (Grok 4.5). The adapter code sources these from the endpoint's reasoning_options field, but that mapping is not documented in the PR body, so the capability claims cannot be reviewed against the cited source without it. Action: Add a sentence to the PR body stating that the /v1/models response's reasoning_options array is the source for each new model's effort values (ideally noting the exact values the endpoint advertises per model), so the non-standard values are directly mapped to the cited endpoint.

[doedja]

Addressed the action item: the PR body now states that effort values are sourced verbatim from the endpoint's reasoning_options array, with a per-model table of the exact values https://kenari.id/v1/models advertises today (re-checked against the live endpoint before posting). Models advertising reasoning: true with no effort list get reasoning_options = [], same as the existing hand-authored entries.
