[BUG] Parameter alignment cache is not updated in real time

[Li12137]

Describe the bug
After editing variable or keyword names in a .robot file, subsequent formatting by RobotCode fails to realign columns based on the current maximum identifier width. This results in misaligned variables in *** Variables *** and keywords in *** Keywords ***. The issue persists until "RobotCode: Reload Workspace" is manually triggered, indicating a caching or incremental update bug in the language server.

Steps To Reproduce
Steps to reproduce the behavior:

1. Create a new .robot file with long-named variables and keywords.
2. Save and format the file (initial formatting works correctly).
3. Edit the file by either:
   • Replacing a long variable name (e.g., ${very_long_variable_name}) with a short one (e.g., ${x}), or
   • Renaming a long keyword (e.g., ThisIsAVeryLongKeywordName) to a short one (e.g., ShortKW).
   • Save the file again (with formatOnSave enabled) or manually trigger format.
4. Observe that the newly edited line is no longer aligned with other entries in the same section.

If possible add some example source code like:

*** Settings ***
Library    Collections

*** Variables ***
${tmp_01}               ${EMPTY}
${tmp_02_02}            ${EMPTY}
${tmp_03_03_03}         ${EMPTY}
${tmp_04_04_04_04}      ${EMPTY}

*** Keywords ***
VeryLongKeywordName     [Arguments]    ${arg1}    ${arg2}
AnotherVeryLongKW       [Arguments]    ${x}       ${y}

add new ${short} and reformatting:

*** Variables ***
${tmp_01}               ${EMPTY}
${tmp_02_02}            ${EMPTY}
${tmp_03_03_03}         ${EMPTY}
${tmp_04_04_04_04}      ${EMPTY}
${short}       ${EMPTY}  # ← Misaligned!

Expected behavior
Formatting should always recompute alignment based on the current content of the section. All variables/keywords in the same block should align to the same column, determined by the longest identifier after edits.

None

Additional context

• Running “RobotCode: Reload Workspace” immediately fixes the alignment, confirming the problem is due to stale internal state/cache in the LSP.
• Formatting works correctly on first open; only breaks after incremental edits.
• VS Code setting explicitly uses RobotCode as formatter:

    "[robotframework]": {
        "files.eol": "\n",
        "editor.defaultFormatter": "d-biehl.robotcode",
        "editor.formatOnSave": true,
    },
    "robotcode.robocop.enabled": false,
