converge more fetchers onto shared lib/gh.js client

[kylerankin]

Migrates three more hand-rolled GitHub API fetchers onto the single adr/0003-endorsed client in scripts/lib/gh.js (#1232), continuing the convergence started for fetch-hive-live-data.js and fetch-factory-stats.js.

What changed — token acquisition, the Accept/api-version/user-agent contract, and the Bearer auth scheme now flow through githubToken() / githubHeaders() instead of being restated per file:

• scripts/fetch-feeds.js — replaces its inline GITHUB_TOKEN||GH_TOKEN read and the 3-line Authorization/Accept/X-GitHub-Api-Version object with githubToken() + githubHeaders(). Link-header pagination and the Atom fallback are untouched.
• scripts/fetch-pin-state.js — goes through githubFetch() with the shared header contract (kept its accept: v3+json override for the Contents API) and its own 15s AbortSignal; still throws on a non-2xx.
• scripts/fetch-hive-history.js — ghHeaders() now builds through githubHeaders() and drops its module-level GITHUB_TOKEN/GH_TOKEN restatement.

Behavior-neutral. Same endpoints, same token source, same timeout/fallback per file — only the auth/header construction is deduplicated. This closes most of the "8 hand-rolled token+header sites" the issue names; the remaining githubHeaders/sequentialFetchWithDelay CJS side (lib/request-queue.js) and the GHCR-specialized lib/sbom/api.js (Basic x-access-token, a genuinely different auth target) are left for follow-up PRs.

Correctness review (head 8c0c99e)

1. Missed call site of now-async ghHeaders() — scripts/fetch-hive-history.js:457. The PR makes ghHeaders() async and awaits it at lines 204 and 389, but the snapshot fetch spreads it un-awaited: ...ghHeaders(). Spreading a Promise yields no properties, so this request silently loses the User-Agent: bluefin-hive-history/1.0 header it previously carried (Authorization/Accept survive because they're set explicitly after the spread). The fetch is wrapped in try/catch and warns rather than fails, so this degrades silently. Fix: ...(await ghHeaders()), or leave this non-GitHub call on a plain literal since it targets the hive API, not GitHub.

2. Dead code + changed error message — scripts/fetch-pin-state.js:46-58. githubFetch defaults to throwOnError: true and throws on non-2xx (lib/gh.js:70-78), so the if (!response.ok) block at lines 54-58 is now unreachable and the thrown message changes from GitHub API error for ${repo}/${filePath}: ... to GET <url> -> <status>, losing the repo/path context. Minor, but the PR body's "still throws on a non-2xx" implies the existing handler still runs — it doesn't. Also token: githubToken() passed to githubFetch at line 47 is a no-op (githubFetch has no token option; auth flows via the pre-built headers) — harmless but worth removing.

fetch-feeds.js changes look behavior-equivalent (Atom fallback and pagination untouched).

Addressed both findings:

1. Missed call site (fetch-hive-history.js:457) — the snapshot fetch was spreading an un-awaited ghHeaders() Promise, silently dropping the User-Agent header. Changed to ...(await ghHeaders()).

2. Dead code + no-op (fetch-pin-state.js) — githubFetch throws on non-2xx (throwOnError defaults true), so the if (!response.ok) guard was unreachable. Removed it and the no-op token: option that githubFetch does not accept. The request still throws on a non-2xx, now via the shared client with its GET <path> -> <status> error.

node --check passes on both files. Re-requesting review.

HUMAN DECISION NEEDED — @kylerankin the migrated snapshot fetch now sends the repo's GITHUB_TOKEN to the third-party hive host and likely breaks snapshot auth; needs a decision on fixing vs. reverting that hunk before merge.

High — GitHub token leaked to non-GitHub host + snapshot auth regression (scripts/fetch-hive-history.js:455-460)

The snapshot call to https://hosted-projectbluefin-knuckle-gjvq.hive.hivecommons.dev/api/status spreads await ghHeaders() and then overrides with Authorization: Bearer <HIVE_API_TOKEN>. The old ghHeaders() used the exact-case key Authorization, so the spread-then-override cleanly replaced the GitHub token. The new githubHeaders() (scripts/lib/gh.js:41-50) emits lowercase authorization, so the override no longer replaces it — both keys survive and undici's Headers joins them:

authorization => Bearer <GITHUB_TOKEN>, Bearer <HIVE_API_TOKEN>
accept => application/vnd.github+json, application/json

(verified with Node fetch Headers). Two consequences:

1. The GITHUB_TOKEN is now transmitted to the hive host — directly contrary to gh.js's own contract comment "Nothing here emits a token, a host address" (scripts/lib/gh.js:12).
2. The mangled joined bearer value will almost certainly 401; the fail-soft catch at scripts/fetch-hive-history.js:465-471 just warns and skips, so snapshot metrics silently stop being recorded.

Since this endpoint isn't the GitHub API at all, the fix is to not use ghHeaders() here — build { "User-Agent", Authorization, Accept } inline for the snapshot call (or add an option to omit the token). This contradicts the PR body's "Behavior-neutral" claim for this file.

Low (scripts/fetch-pin-state.js:52-60): error text on non-2xx changes from GitHub API error for <repo>/<path>: <status> <statusText> to githubFetch's GET <url> -> <status> — URL is retained so context survives; noting only because the PR body says the throw behavior is "kept".

Everything else checks out: githubToken() returns null so the fetch-feeds.js:69-72 no-token Atom fallback still triggers; fetch-pin-state.js keeps its v3+json accept override and 15s abort signal; all three ghHeaders() call sites in fetch-hive-history.js were updated to await; importing lib/gh.js (which imports fetch-factory-stats.js) is side-effect-free due to the main-module guard at fetch-factory-stats.js:366.
