Subject: [PATCH] perf: Fix double initialization of Date in dossier compiler

Extracted the Date initialization into a variable so `new Date().toLocaleString()` or `new Date(item.timestamp).toLocaleString()` isn't executed twice within the ternary condition.
Also applied the fix to both the CommonJS (`.cjs`) and ES Module (`.js`) versions of the shared compiler code.

Benchmark improvement measured: test3 (using `item.timestamp || Date.now()`) showed roughly a ~55% speedup (1071ms down to ~474ms) against the original implementation for 100k ops.
