Resolve public model identities and prepare v0.11.0

[kwisatzh]

Summary

• Prepare fleetdiff v0.11.0 with readable public model IDs and explicit --show-labels for local route/agent configuration labels.
• Share one exact catalog match between labels and what-if pricing. Qualified names require agreement between their prefix, the row provider and the catalog provider.
• Fix v0.10.1 excluding provider-qualified model rows as unknown prices. Preserve token totals, grouping, keyed identities, unknown coverage and private-name aliases.
• Keep a distinguishing alias when separate source groups resolve to the same public ID.
• Update release notes, installer/version expectations and the routing guide. No measured-factor or pricing-rate changes.

Checks

• Reproduced the released pricing defect with the pinned LiteLLM writer, PostgreSQL and SQL export, using only synthetic data and no provider calls.
• Full race tests, vet, legacy output/hash goldens, privacy and structured-match tests; independent review of the matcher and collision handling.
• Pinned SQL/database and old-reader compatibility suite; factor reproduction; bounded fuzz smoke; 14 network-disabled binary cases.
• Anonymous source-candidate guide check with fresh caches; packaged regression for scoped and unscoped structured-model pricing.
• Release publication remains subject to final-head hosted CI, artifact verification and released-binary outsider checks.
