feat(linear): add getTeams, getTeamWorkflowStates, getTeamLabels discovery methods

[aaight]

Summary

• Add linearClient.getTeams() — returns all teams accessible by API key as LinearTeam[]
• Add linearClient.getTeamWorkflowStates(teamId) — returns workflow states for a team as LinearWorkflowState[]
• Add linearClient.getTeamLabels(teamId) — returns labels for a team as LinearLabel[]

These discovery methods are required by the dashboard PM wizard to let users select a team and map workflow states during Linear setup.

Implementation Details

• Follows the existing GraphQL query + mapper pattern used by getIssue() / listIssues() and other methods
• Reuses existing GraphQL field fragments (TEAM_FIELDS, STATE_FIELDS, LABEL_FIELDS) and existing mappers (mapTeam, mapState, mapLabel)
• Imports LinearTeam and LinearWorkflowState types from src/linear/types.ts (types already existed)
• No changes to src/linear/types.ts — all required types were already defined

Tests

• 18 new unit tests in tests/unit/pm/linear/client.test.ts
• Coverage for all 3 methods: success cases, empty results, missing field defaults, variable passing, GraphQL errors, and HTTP errors

LGTM — Clean, pattern-consistent addition of three discovery methods that reuse existing GraphQL fragments, mappers, and the linearGraphQL helper. Implementation follows the exact same conventions as getIssue()/listIssues() and other methods in the file. Types (LinearTeam, LinearWorkflowState) were already defined in types.ts, so no type changes were needed. Test coverage is thorough (18 tests covering success, empty results, missing field defaults, variable passing, GraphQL errors, and HTTP errors). All CI checks pass.
