feat: platform tab anchors at PlatformManifest + export CL_ANCHOR

Group/cross-repo tabs now cd into PlatformManifest instead of the bare
~/Documents/GitHub root, and the claude wrapper exports CL_ANCHOR=<cwd> so
OC-launched sessions satisfy ContextLifecycle's guard hooks (which now
hard-require CL_ANCHOR with no CWD fallback). Adds anchor-launch tests.

+## 2026-05-24 — Platform tab anchors at PlatformManifest + export CL_ANCHOR
+
+- launcher._multi_pane_block: cross-repo group tab cwd → PlatformManifest (was bare ~/Documents/GitHub). git-watcher still spans all group repos.
+- bootstrap.get_claude_command: wrapper now exports CL_ANCHOR=<cwd> so OC-launched sessions satisfy the CL guard hooks (which now hard-require CL_ANCHOR, no CWD fallback). Single-repo tabs anchor at their repo; group tab at PlatformManifest.
+- Added tests/test_anchor_launch.py (2 tests). NOTE: pre-existing test_watcher_pane.py failures are unrelated (confirmed on clean main).
