chore(security): add a gitleaks allowlist for triaged false positives

The gitleaks gate has been blocking this repository's pull requests. Every
finding was triaged on 2026-08-06 by reading the matched line with the value
redacted, and every one is a false positive. No live credential was found.

Each entry names WHAT THE VALUE ACTUALLY IS rather than saying the file is
noisy — an algorithm name, a bibliographic key, a published protocol
constant, a fixture belonging to a secret DETECTOR, and so on.

The file EXTENDS the estate baseline rather than replacing it:
hyperpolymath/standards secret-scanner-reusable.yml stages that baseline at
the workspace root as .gitleaks-estate.toml, and gitleaks resolves
'[extend] path' against the process CWD. Requires standards#584.

Kept local rather than promoted to the estate baseline because every entry is
a blind spot: held here it blinds this repository only, with its
justification beside the code it describes.

Verified before commit: with this config in place a planted AWS canary
outside the exempted paths is still DETECTED and the gate still exits
non-zero on it.

+# Every entry below is a blind spot. Held here, it blinds this repository only,
+# and the justification sits beside the code it describes. Promoted to the
+# estate baseline it would blind all 400+ repositories — so the baseline keeps
+# only entries that are true everywhere (lockfiles, vendored bundles, published
+# protocol constants).
+#
+# Each entry names WHAT THE VALUE IS. "This file is noisy" is not a reason; if
+# an entry cannot say what the matched value actually is, the secret should be
+# removed from the tree instead.
+#
+# Every finding suppressed here was triaged on 2026-08-06 by reading the
+# matched line with the value redacted. Before adding an entry, plant a
+# realistic secret in the same path and confirm it is STILL detected.
