Remove third-party disambiguation agent and matching

The tracker-mapping worker no longer auto-creates or auto-links org
third parties, so the heuristic ranker, the disambiguation agent, and
the catalog-to-org seeding helpers are dead code.

Delete pkg/thirdparty/match.go (RankCandidates, ScoredCandidate,
LinkToCommon, CreateFromCommon, suffix stripping, score thresholds) and
disambiguation_agent.go, along with their tests. Drop the
ThirdPartyDisambiguation agent slot and the worker's
DisambiguationAgentTimeout from probodconfig, the builder env wiring, and
the builder tests.

Remove the matching helm surface too: the thirdPartyDisambiguation agent
values, the disambiguationAgentTimeout worker tuning, and the
AGENT_THIRD_PARTY_DISAMBIGUATION_* / TRACKER_MAPPING_DISAMBIGUATION_AGENT
_TIMEOUT environment mappings, with a chart changelog note. The probod
config is built from env lookups with defaults, so a lingering value in
an older deployment is simply ignored.
