Fix JS Programming decompiler replacing spaces with variable names

**Problem:**
When decompiling logic conditions with activator hoisting and a stored
variable map, all spaces between words were being replaced with custom
variable names (e.g., "const min" became "constmin", comments like
"INAV JavaScript Programming" became "INAVminJavaScriptminProgramming").

**Root Cause:**
In decompiler.js applyCustomVariableNames() at line 293, the code was
storing entire objects from hoistedActivatorVars instead of extracting
the varName string:

  const entry = { varName: 'cond1', scopeLcIndex: -1 }

When this object was used in a template literal to build a regex pattern:
  `\\b${entry}\\b` → `\\b[object Object]\\b`

In regex, `[object Object]` is a CHARACTER CLASS that matches any single
character from the set: {o,b,j,e,c,t,space,O}. This caused the regex
pattern `\\b[object Object]\\b` to match spaces between word boundaries,
replacing them with the custom variable name.

**Fix:**
Changed line 293-294 to extract the .varName property:
  - Before: lcIndexToGeneratedName.set(lcIndex, generatedName);
  - After: lcIndexToGeneratedName.set(lcIndex, entry.varName);

This ensures the regex replacement uses the actual variable name string
instead of "[object Object]" character class.

**Files Changed:**
- js/transpiler/transpiler/decompiler.js

**Testing:**
Verified with test cases showing the fix prevents space replacement in
both code and comments.
