Equation solving with Ctrl+Space stops in note editor

[pbek]

Equation solving in the note text edit no longer works reliably with Ctrl+Space when note editing is disabled/read-only mode is active. Example: typing 1+1= and pressing Ctrl+Space prompts/enables editing but does not continue to the equation-solving autocomplete flow, so no result can be inserted.\n\nExpected behavior: after editing is allowed, Ctrl+Space should continue with the normal autocomplete/equation-solving flow and offer the result for insertion.

Root cause updated while testing: Markdown LSP completion could also return before the equation solver was reached, so 1+1= with Ctrl+Space only logged the empty URL check and did not show the calculator result. The fix makes equation detection run before LSP completion and keeps the editing-disabled path from returning early after editing is allowed.
