feat(agent): deprecate and completely remove cline agent support

- Delete adapters/cline.py and unregister from registry.py
- Remove cline branches from lib.sh and all 8 skill scripts (create, resume, stop, status, reconcile, update_yaml_resumed, resolve_session_id, orc_onboard)
- Narrow own-key mapping dictionaries across lib_py core modules to 4 supported agents
- Delete cline-exclusive tests and retarget shared fixtures to grok/hermes/claude
- Update skills documentation and installation guides (439 passed, 0 failures)
- Archive cline deprecation consensus and review reports

+# Re-review: `cline_deprecation_opinion.md` (Rev.3)

+- **Reviewer**: `reviewer-creator-grok-01`
+- **Job**: `d1fe1a99` (follow-up to `0a056794` `[VERDICT: NOT PASS]`)
+- **Artifact**: `.agents/reports/cline_deprecation_opinion.md` (untracked; no skill/framework code in the diff)
+
+## Prior blocking items
+
+| ID | Rev.2 defect | Rev.3 |
+|---|---|---|
+| **F1** | Claimed no `--api-key`-override exists | **Fixed.** §3.2 and §6.2 cite `-k, --key <api-key>` as spawn/run-start injection, bound as not mid-task refresh / not modal suppression. `--headless`/`--non-interactive` absence still holds against live `cline --help`. |
+| **F2** | Claimed claude drift-C has `sibling_claimed` | **Fixed.** §2.3 / §6.1: only agy (~692) and hermes (~742); claude (~637) and cline (~785) both lack it. |
+| **F3** | “All three independently demand a drift-C fix either way” | **Fixed.** Hermes: condition of RETAIN. Planner: urgent if RETAIN. Grok: delete the block if REMOVE. |
+
+## Remainder (non-blocking)
+
+- Honest 2–1 split preserved. Grok **REMOVE** in §1/§4 is accurate (no assignable UUID; unattended/modal gap; no live cline session).
+- §5 blast-radius constraints still match `e0916903` (keep `_pane_quiescent` / paste-normalize; retarget `test_c1_*`; no drive-by `cline.py` delete).
+- §2 heading still says “fully agree” while point 3 now states a disposition split. Content is honest; heading is slightly loose. Not worth another loop.
+- Grok’s **REMOVE** vote is unchanged. This PASS is on the synthesis, not a vote flip.
+
+No `[ESCALATE: PLANNER]`. GM still owns REMOVE vs conditional-RETAIN.
