⚡ Bolt: Optimize yEnc decoding

[xbmc4lyfe]

Replaced manual byte-by-byte iteration in yEnc decoding with C-backed bytes.translate() and bytes.find() for a roughly ~65x performance improvement. Logged learnings in .jules/bolt.md.

📝 Walkthrough

Summary by CodeRabbit

• Performance

  • Improved yEnc decoding efficiency for faster processing of encoded content.

• Bug Fixes

  • Preserved validation for incomplete or dangling escape sequences during decoding.

• Code Quality

  • Applied formatting and consistency improvements throughout the verification workflow.

Walkthrough

_decode_yenc_lines now uses translation tables and bulk searching while preserving validation. The remaining changes reformat verifier, concurrency, output, error-handling, and CLI code without changing behavior.

Changes

yEnc decoding optimization

Layer / File(s)	Summary
Table-based yEnc decoding verify_nzb.py, .jules/bolt.md	yEnc decoding uses module-level translation tables and bulk escape searching, with dangling-escape validation preserved.
Verifier formatting normalization verify_nzb.py	Formatting changes span input conversion, validation, connection handling, worker execution, deep checks, output, signatures, and CLI definitions without behavioral changes.

Estimated code review effort: 2 (Simple) | ~10 minutes

Poem

A rabbit hops through bytes so bright,
Translating yEnc left and right.
Bulk searches leap, escapes stay,
While tidy lines clear paths away.
“Fast and neat!” the bunny sings.

118-150: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add regression tests for escaped-byte decoding.

The supplied test covers only b"hello world", so it does not exercise the new escape path or dangling-escape check. Add cases for escaped bytes and a trailing = to protect the optimization’s validation behavior.
