cloudflare-ddns v2.1.2 — Notification & Domain Casing Fixes

This patch release fixes three bugs reported on GitHub.

Bug fixes

• Mixed-case domains now match existing DNS records (#255).
  In env-var mode, configuring a domain with mixed casing (for example
  ExaMple.com) caused every update cycle to attempt a duplicate record
  create and fail with Cloudflare error 81058: An identical record already exists. Cloudflare normalizes record names to lowercase server-side, so
  the lookup is now case-insensitive.

• Pushover notifications work again (#258).
  The shoutrrr-style URL pushover://shoutrrr:TOKEN@USER (the canonical form
  from containrrr/shoutrrr) was being parsed with the literal shoutrrr:
  username included in the API token, which Pushover rejected. The parser
  now strips the optional <user>: prefix from the token segment, restoring
  the v2.0.7 behavior. Optional shoutrrr query parameters (?devices=...,
  ?priority=...) are tolerated.

• Gotify notifications now produce a valid request URL (#262).
  The Gotify URL parser blindly appended /message after any query string,
  producing malformed webhook URLs like
  https://host:9090?token=XYZ/message. The parser now follows shoutrrr's
  canonical layout — token as the final path segment or ?token= query —
  and supports ?disabletls=yes to switch the resulting webhook from HTTPS
  to HTTP for typical home-LAN setups, plus the gotify+http:// /
  gotify+https:// aliases.

Already addressed (closing #257)

The robust public-IP discovery enhancements requested in #257 (multi-endpoint
trace fallback, strict address-family validation, API request timeouts,
duplicate record cleanup) were already folded into the Rust port shipped in
v2.0.8 — see src/provider.rs (CF_TRACE_PRIMARY / CF_TRACE_FALLBACK,
validate_detected_ip, build_split_client) and src/cloudflare.rs
(set_ips dedup behavior, per-request timeout).
