[codex] Document COMSOL Java Shell deprecation

[jiweiqi]

Summary

• Clarify that an already-open COMSOL Desktop is not a reason to use Java Shell or GUI automation.
• Add issue Avoid launching a second shared Desktop client when attaching to an existing mphclient session #32 routing guidance: if the user already owns a comsolmphserver + mphclient session, attach with --ui-mode no_gui --driver-option attach_only=true instead of launching another Desktop client.
• Re-home the useful stash notes as server-backed JPype/COMSOL Java API guidance: Box selection entitydim ordering and keeping provenance out of global parameter values.
• Refresh uv.lock so the editable package version matches pyproject.toml at 0.1.14 instead of preserving the stale stash 0.1.13 change.

Why

This keeps the supported COMSOL control planes clear: server-backed JPype for live structured work, plugin-owned shared-desktop for managed Model Builder collaboration, comsolbatch for settled recipes, and offline .mph inspection for saved artifacts. Java Shell / ordinary Desktop attach remains deprecated and unsuitable as acceptance evidence.

Validation

• git diff --check
• uv lock --check
• Scanned the COMSOL skill docs for remaining Java Shell/shared-desktop routing language.
