chore(security): clear 3 audit advisories via yarn resolutions

Apply selective version resolutions for transitive deps where the
bump is semver-compatible AND only one major exists in the tree.
Skips multi-major cases (picomatch 2.x+4.x, minimatch 3.x+5.x+9.x+
10.x, glob 7.x+11.x), axios (needs graph-cli upstream), and lodash
(advisory affects all of 4.x, no fix without major migration).

Resolutions added (root package.json):
  immutable:    5.1.4              -> ^5.1.5  (advisory 1117068)
  cross-spawn:  7.0.3 + 7.0.6      -> ^7.0.6  (advisory 1104664)
  semver:       7.3.5 + 7.7.x      -> ^7.5.2  (advisory 1112921)

Effect on root yarn.lock: dedups cross-spawn (-2 entries), bumps
immutable (1 patch) and semver 7.3.5 (-> 7.7.4 via existing range).
Net -50 lines in yarn.lock.

Allowlist trimmed from 23 -> 20 entries. Audit script's drift
detector flagged the now-cleared advisories as warnings before
trim, then exited clean after.

Verification:
- Root: yarn install --frozen-lockfile clean; yarn audit:prod OK
  (20 allowlisted, no unlisted high/critical).
- All 13 paths: yarn install --frozen-lockfile "Already up-to-date"
  (subgraph lockfiles untouched — root resolutions don't propagate).
- Smoke test: predict-omen (19/19 tests pass), babydegen-optimism
  (10/10 tests pass) — same counts as PR2's verification.

Out of scope (left in allowlist with 90-day review):
- 5x axios advisories (need graph-cli upstream migration to axios 1.x)
- 3x minimatch (multi-major in tree — risky to force one)
- 3x undici, 1x picomatch, 1x lodash, 1x glob
- Total: 20 remaining entries, all reviewed 2026-08-05
