chore: pin merged Lotus Next actor UI source (#295)

[bigduu]

Summary

Pin the merged Lotus Next actor UI source chain in the Zenith wrapper. This is a source-pointer update only; it does not publish or adopt a new frontend artifact and does not claim live Bamboo integration or completion of the related partial UI Issues.

• Zenith base: main at 30d21eccc3533717f8d0afe4ab3da1f9e559cd95.
• PR head: a99f74b8d9573a52e63acf1201a3d073e939c70d.
• Lotus Next target: merged remote main at cdc226031079063b517fbf862037f7dac4aaad83.

Submodule Updates

• lotus-next (160000): e8d7e7f5f3807393093da0f06b5af40a1acac22d → cdc226031079063b517fbf862037f7dac4aaad83. This advances the wrapper to the merged Lotus Next actor UI source for the work tracked by Lotus Next [zenith] chore: pin reviewed Jiandu memory service #194, chore: pin reviewed Jiandu memory service (#194) #195, chore: pin Bamboo context file export #196, [zenith] chore: pin Jiandu Settings management #197, [zenith] tracker: observe Jiandu prompt activation to guide memory optimization #199, chore: pin Jiandu Settings management (#197) #198, chore: adopt Nova live resident application discovery #202, and chore: pin Bamboo SQLite optimizations (#200) #201. The old commit is an ancestor of the new remote main commit.
• No other gitlink or file changes.

Test Plan

• Verified exact Lotus Next remote main SHA and old-pointer ancestry (ahead_by=80, behind_by=0).
• Verified git ls-tree before/after and git diff --raw / git diff --name-only: only the lotus-next mode-160000 entry changed.
• git diff --check HEAD^ HEAD passed; worktree clean.
• Zenith Submodule Guard must pass on this exact PR head before merge. Local independent pointer review is complete; no GitHub review is requested.

Release boundary

Zenith's committed release configuration still locks @bigduu/lotus-next@2026.9.22 to source a480e2bb94f5dd08fe4b01b2f8844a2c9ed03245. This PR leaves that configuration, Bamboo and Bodhi pointers unchanged. A later immutable artifact and consumer acceptance must reconcile the release snapshot before a release is claimed.

Screenshots

Not applicable: this PR only changes a Git submodule pointer.
