docs(miner): document miner_claims schema in claim ledger

[kiannidev]

Summary

• Document the foundation-phase miner_claims schema inline above the CREATE TABLE: repo_full_name, issue_number, claimed_at, status CHECK (active/released/expired), and UNIQUE (repo_full_name, issue_number).
• Note that release/expire timing is captured via status transitions rather than a separate released_at column (the shipped schema extends the original sketch with expired for TTL expiry).
• Add a source-doc regression test so the schema comment cannot drift silently.

Closes #3352

Test plan

• test/unit/miner-claim-ledger.test.ts — Schema: repo_full_name TEXT NOT NULL, issue_number INTEGER NOT NULL, status TEXT NOT NULL CHECK(status IN ('active','released')), claimed_at TEXT NOT NULL, released_at TEXT, PRIMARY KEY (repo_full_name, issue_number). #3352 schema doc assertion (15 tests total)
• npm run build --workspace @jsonbored/gittensory-miner

🛑 Suggested Action - Fix Blockers

Review summary
This is a pure documentation PR: it adds a comment block above the `miner_claims` CREATE TABLE in claim-ledger.js:81-95 spelling out the columns, the status CHECK values, and the UNIQUE constraint, plus a regression test that greps the source file for those exact strings so the comment can't silently drift. The documented schema (columns, CHECK values, UNIQUE constraint) matches the real CREATE TABLE below it, and the PR closes the linked issue #3352 as required. It's low-risk, narrowly scoped, and correct as written; the only gap is the comment omits the `DEFAULT 'active'` clause that's actually in the CREATE TABLE.

Nits — 5 non-blocking

• The new schema comment (claim-ledger.js) omits `DEFAULT 'active'`, which the real CREATE TABLE has on the `status` column — worth adding for completeness since the whole point of this PR is an accurate inline schema doc.
• The regression test (miner-claim-ledger.test.ts) asserts brittle exact-whitespace substrings (e.g. `CHECK(status IN (...))` with no space, differing from the actual DDL's `CHECK (status IN (...))` with a space) — any future reformatting of the comment (even a harmless one) will break this test for no functional reason.
• The test only checks that certain substrings exist in the file; it doesn't verify the documented CHECK values/UNIQUE columns actually match the live CREATE TABLE, so the two could drift apart again without failing this test.
• Add `DEFAULT 'active'` to the schema comment in claim-ledger.js so it fully mirrors the CREATE TABLE.
• Consider deriving the test assertions from the actual CREATE TABLE string (e.g. slicing the source between markers) rather than hardcoding parallel literal strings, so the test fails only when documentation and implementation genuinely diverge, not on incidental formatting changes.

• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
