Unrelated third-party trackers that happened to share a leading
separator run (e.g. __support__, __darkreader__wasEnabledForHost,
__EXT_APP_REFRESH_BLACK_SUB_DOMAINS__) were being merged under
overly broad globs such as __* because templateCandidates emitted
every prefix at each '_' or '-' position without requiring any
fixed anchor.
Add a templateHasFixedAnchor helper and apply it to both
templateCandidates loops and the heuristicTemplate result so
candidates consisting solely of '_', '-', and '*' are rejected.

splitTokens previously picked a single separator (_ winning over -).
Cookies like __Secure-1PSID were split on _ only, leaving
"Secure-1PSID" as one token that falsely passed looksVariable,
producing the bogus ___* heuristic pattern.
The function now splits by _ first, then sub-splits each non-UUID
part by -, tracking per-gap separators. heuristicTemplate trims
leading/trailing empty tokens before analysis so that prefix
underscores are preserved in the output but do not pollute the
variable detection.

Move tracker_mapping_worker.go from pkg/probo to pkg/cookiebanner and
rename worker.go to pattern_analysis_worker.go to reflect the worker
name.
