The alias removal left bridge_* tool names in prose. Fix them:
- README no longer claims the old bridge_* names still answer (they were removed).
- pom + LeadTabScanner comments name fleet_* tools.
- FleetMcp comment no longer mentions the removed deprecated twin.
- docs/MCP-Contract.md and e2e swept bridge_* -> fleet_*; e2e ask files renamed.
The historical mcp__bridge__* mount-name note in CLAUDE.md is kept on purpose.
949 tests pass.
