feat(reset-timer): show local timezone clock time alongside countdown (#34)

[guyinwonder168]

Summary

Resolves #34

The reset timer previously showed only a countdown (4h 36m), leaving users in far-from-UTC timezones unable to tell when resets actually occur. This PR adds the local clock time alongside the countdown.

Changes

Output Format

Before:

| ⏱️ 5h Token | 87.0% | ████████████████░░░░░ | 4h 36m |
| 📅 Weekly   | 17.0% | ████░░░░░░░░░░░░░░░░ | 6d 16h |

After:

| ⏱️ 5h Token | 87.0% | ████████████████░░░░░ | 4h 36m (01:34) |
| 📅 Weekly   | 17.0% | ████░░░░░░░░░░░░░░░░ | 6d 16h (Sat 13:48) |

Implementation

• formatResetCell() in src/index.ts uses native Date methods (getHours(), getMinutes(), getDay())
• Short durations (<24h): 4h 36m (HH:MM)
• Long durations (≥24h): 6d 16h (Day HH:MM)
• No timezone abbreviations (unreliable in Node.js across platforms — user knows their own TZ)

Testing (TDD)

• Integration tests updated to use assert.match() with regex patterns for timezone-independent matching
• Pattern: /\d{2}:\d{2}/ for short, /[A-Z][a-z]{2} \d{2}:\d{2}/ for long durations
• 117 tests passing, 0 failures

Documentation

• New: docs/implementation-plan-v1.8.0.md
• Updated: CHANGELOG.md, README.md, docs/opencode-glm-quota-prd-final.md (Section 1.12)
• Updated: AGENTS.md — added KISS/YAGNI/TDD/No-Over-Thinking development principles

Version

• 1.7.0 → 1.8.0 (MINOR — new user-visible feature)

Design Decisions (KISS + YAGNI)

Decision	Choice	Why
TZ abbreviation	Not included	toLocaleTimeString TZ names unreliable across platforms
Time API	Native Date methods	No dependencies, follows existing date-formatter.ts pattern
Test strategy	Regex assertions	Deterministic across CI environments (defaults to UTC)

Checklist

• TypeScript builds clean
• ESLint passes (0 errors)
• All 117 tests pass
• CHANGELOG updated
• README output example updated
• PRD Section 1.12 added
• Version bumped in package.json + sonar-project.properties
