fix: resolve open-issue cluster (#2295, #2298, #2303–#2306, #2340) + createdTime fallback bug (#2408)

* fix: resolve issue cluster (#2295,#2298,#2303,#2304,#2305,#2306,#2340) + createdTime fallback bug

- session-manager: fix createdTime birthtime||ctime fallback that never fired
  (a Date is always truthy); use birthtimeMs>0 check via resolveCreatedTime()
- installer: rewrite source-relative rules/skills links for the injected
  ecc/ namespace so installed skills resolve correctly (#2340)
- continuous-learning-v2: drop unused mock import (#2305); standardize bash
  shebangs (#2303); poll for PID file instead of fixed sleep (#2295);
  rename _ecc_* -> _clv2_* (#2304); align promotion confidence docs (#2298);
  de-brittle Scope Decision Guide cross-reference (#2306)

* fix(ci): resync lockfiles with package.json (eslint 10) + migrate yarn.lock to Yarn 4 format

package.json requires eslint@^10.6.0 but the committed locks pinned 9.39.2, so
npm ci aborted and Yarn 4 hardened mode rejected the stale v1-classic yarn.lock
(YN0028). Regenerate package-lock.json and rewrite yarn.lock in Yarn 4 (berry)
format so npm ci and immutable yarn installs both pass.
