TASK 56: the secret scan is done - and the history is clean

The release gate before the repo goes public. Scanned 432 reachable commits (all
branches, 35 tags, the reflog, refs/stash) + the 63 dangling commits git fsck still
holds + every tracked file in the worktree, for Google OAuth client secrets, API
keys/tokens (Polar OAT, ghp_, AKIA, Slack, Stripe, OpenAI), private-key headers,
assigned credentials, and any once-tracked CREDENTIALS.md / OAuthCredentials.cs /
MARCOM.md. Report format is commit + path + rule only - no matched value ever
reaches the screen.

Result: 4 hits, ALL false positives - README.md:79 is the doc snippet's
'ClientSecret = your-client-secret' placeholder, TokenStoreTests.cs:22 is a 9-char
test dummy. Nothing to rotate, no history rewrite. The three secret files were
never tracked.

Also recorded: the repo was ALREADY public when the scan ran (anonymous GET -> 200,
API private=false), so the gate came late - but nothing leaked. The creator still
owns the keep-it-public decision.

Method + verdict in TASKS/task-56-secret-scan.md; the reusable recipe in
MyMistakes.md -> 2026-10-22.
