fix(baseline): unblock 2 baseline-rot checks blocking dependabot #69 (#70)

## Summary

Two CI checks have been failing on \`main\` for several days, poisoning
every inbound PR including the approved dependabot SHA bump in #69.

### Validate K9 contracts (RESOLVED)

\`absolute-zero/coordination.k9\` was a 54-line markdown-format
coordination protocol document misnamed with the \`.k9\` extension. The
K9 validator expects K9-contract format (\`K9!\` magic, \`pedigree = {
... }\` block), so it failed with:

    ##[error]Missing K9! magic number
    ##[error]Missing pedigree block

Renamed → \`absolute-zero/COORDINATION.md\`. Content unchanged; only the
extension. K9 validator now finds zero \`.k9\` files in the repo and
skips cleanly.

### Language / package anti-pattern policy (RESOLVED via exemption)

5 banned-language files in nested \`absolute-zero/\` and \`aletheia/\`
subdirs:
- \`absolute-zero/src/AuditTrail.res\`
- \`absolute-zero/interpreters/rescript/malbolgeInterpreter.res\`
- \`absolute-zero/examples/SafeDOMExample.res\`
- \`aletheia/examples/SafeDOMExample.res\`
- \`absolute-zero/examples/go/nop.go\`

These are vendored under subdirs of this monorepo and do **not** appear
in the standalone upstream repos (verified via local file-existence
check). They pre-date the estate-wide ReScript→AffineScript migration.

Added \`.hypatia-ignore\` listing each via the exact format the
governance check honours (\`cicd_rules/banned_language_file:<relpath>\`
per \`grep -qxF\` lookup in
\`hyperpolymath/standards/.github/workflows/governance-reusable.yml\`).
File carries a \`TODO 2026-Q3: migrate to AffineScript\` comment to keep
the migration work visible.

## Why a baseline-fix PR

PR #69 (the dependabot SHA bump you approved) inherits this broken
baseline. The dependabot diff is innocent — it just bumped a Rust
toolchain SHA. After this PR merges, #69 should auto-merge or at least
flip to MERGEABLE.

## Companion PRs already landed

This is the same kind of baseline rot we cleared this session in
rsr-template-repo (#69), me-dialect (#1), ambientops (#83), and
rescript-ecosystem (#2).
