chore: advance Lotus Next transport and realtime foundation pointer (#163)

[bigduu]

Summary

• Advance the single lotus-next gitlink from the previously reviewed foundation at 56db603f28b1244c989d8e40b997418b37fbc562 to current Lotus Next main@b0bc55f63d786e01c902984835218f7789e3b0cb.
• Bring fresh Zenith checkouts onto the accepted canonical HTTP transport kernel from Lotus Next docs: allow agent merges after live gates #20 / PR docs: align agent review label #21 and acknowledged half-open WebSocket recovery from Lotus Next chore: bump bamboo permission config foundation #22 / PR chore: bump bamboo permission policy pointer #23.
• Leave every other submodule pointer and every root file unchanged.

Closes #163

Submodule Updates

Submodule	Old SHA	New SHA	Rationale
lotus-next	56db603f28b1244c989d8e40b997418b37fbc562	b0bc55f63d786e01c902984835218f7789e3b0cb	Advance one root gitlink over two separately reviewed and merged Lotus Next slices: typed/cancellable safe HTTP transport (40dac3f) and epoch-safe half-open WSS recovery (b0bc55f). The diff is intentionally one pointer even though the upstream range contains both accepted commits; no intermediate root pin is needed.

Verification

• Fresh isolated worktree started at exact Zenith origin/main@001727fd7b4227c93e0edc4b45b52f015e8d50f1.
• git diff --cached --raw before commit showed exactly one mode-160000 update: lotus-next 56db603 -> b0bc55f.
• git diff --check origin/main...HEAD passed.
• The new gitlink equals live bigduu/lotus-next main@b0bc55f63d786e01c902984835218f7789e3b0cb.
• Lotus Next PR docs: align agent review label #21 exact head eaaf10a and PR chore: bump bamboo permission policy pointer #23 exact head c4ca62c both received independent APPROVE results and exact-head Node 22/24 success before merge; Issues docs: allow agent merges after live gates #20 and chore: bump bamboo permission config foundation #22 are closed and Roadmap Done.
• Zenith Submodule Guard and an independent exact-head root review must pass before merge.

Test Plan

• git diff --check origin/main...HEAD
• git diff --raw origin/main...HEAD
• git diff --name-only origin/main...HEAD
• git ls-tree HEAD lotus-next
• Verify every non-target origin/main gitlink remains byte-for-byte unchanged.
