fix(zilean): percent-encode DMM query titles

[slawrensen]

Summary

• percent-encode the Zilean query parameter so titles with spaces, parentheses, &, +, and non-ASCII characters are sent safely
• keep the change surgical by only wrapping request.title with urllib.parse.quote(..., safe='')
• preserve the existing season / episode query parameters by leaving the show suffix untouched

Why

• comet/scrapers/zilean.py currently interpolates request.title directly into the URL query string
• raw interpolation can produce malformed or truncated lookups when titles contain URL-sensitive characters
• percent-encoding the title makes /dmm/filtered?query=... requests deterministic without changing behavior for simple titles

Notes

• this change is intentionally scoped to zilean.py
• a similar raw query-string interpolation pattern exists in comet/scrapers/prowlarr.py; that can be handled separately

Walkthrough

Added URL encoding to the query parameter in the Zilean scraper's /dmm/filtered request. The quote function is imported and applied to request.title with safe='' to ensure proper URL encoding of the title parameter.

Changes

Cohort / File(s)	Summary
URL Parameter Encoding comet/scrapers/zilean.py	Added quote import from urllib.parse and updated query parameter construction to URL-encode request.title using quote(request.title, safe='') for the /dmm/filtered request.
