fix(fancy): replace width-1 icons for start and trace to fix timestamp alignment

[terminalchai]

Fixes #394

Root Cause

The fancy reporter calculates timestamp alignment using stringWidth(left) where left includes the type icon. All type icons have a string-width of 2:

Type	Icon	string-width
error/fatal/fail	✖	2
ready/success	✔	2
warn	⚠	2
info	ℹ	2
debug	⚙	2
start	◐	1 ← outlier
trace	→	1 ← outlier

Because start and trace icons have string-width 1 while every other type has 2, the space calculation in formatLogObj gives them one extra space — shifting their timestamp one character to the right.

Fix

Replace the two outlier icons with ones that have string-width 2:

• start: ◐ (U+25D0, sw=1) → ▶ (U+25B6, sw=2) — play/run fits the semantic perfectly
• trace: → (U+2192, sw=1) → ➡ (U+27A1, sw=2) — same directional meaning

Before / After

// Before
ℹ I am a info message              1:42:22 am
✔ I am a success message           1:42:22 am
◐ I am a start message              1:42:22 am  ← shifted right by 1

// After
ℹ I am a info message              1:48:11 am
✔ I am a success message           1:48:11 am
▶ I am a start message             1:48:11 am  ← aligned ✓

Summary by CodeRabbit

• Style
  • Improved visual indicators in logs: trace entries now display with an arrow symbol (➡), and start entries with a play symbol (▶) when Unicode is supported.

📝 Walkthrough

Walkthrough

Updated Unicode icons in the fancy reporter's log type symbols. The trace log type now displays "➡" instead of "→", and the start log type displays "▶" instead of "o", with fallbacks for environments without Unicode support.

Changes

Cohort / File(s)	Summary
Icon Updates src/reporters/fancy.ts	Updated TYPE_ICONS for trace and start log types to use improved Unicode symbols (➡ and ▶ respectively) with fallback characters for non-Unicode environments.

🐰 A rabbit hops with glee,
New arrows mark the way we see,
Trace flows with ➡ so fine,
Start plays with ▶ in line,
Our logs now shine, aligned and free! 🌟
