feat: add admin /logs command to view bot log lines

[BigMichi1]

Summary

Adds a new admin-only /logs slash command that displays the last N lines of the bot's combined.log file directly in Discord.

Changes

• src/bot/commands/logs.ts — New /logs command
  • Admin-only (ManageMessages permission, same gate as /backfill)
  • Optional lines integer parameter (1–100, defaults to 20)
  • Reads the tail of logs/combined.log and returns it in a code-block embed (ephemeral)
  • Gracefully truncates content that would exceed Discord's 4096-char embed limit
• src/bot/bot.ts — Import and register logsCommand
• src/bot/commands/help.ts — Add /logs entry to the help embed

Tests

• src/bot/commands/logs.test.ts — 10 new tests (292 total, up from 282)
  • Permission denied path
  • Missing log file → "No log entries found"
  • Default 20 lines
  • Custom N lines — correct tail shown, earlier lines excluded
  • Code-block wrapping
  • Truncation stays within 4096 chars, title marked "truncated"
  • Error handling when readFileSync throws

Coverage for logs.ts: 100% functions / 98.61% lines. No existing file coverage decreased.
