feat: upstream generic workspace tooling (board-sync, crm audit, catalog names)

Promote the generic, reusable parts of the private oo-workspace into the
public library/CLI, so oo-workspace can shrink to business glue.

- board.go: Board types + (c *Client) SyncBoard — upsert project
  milestones/tasks by exact title from a YAML board (dry-run when
  apply=false). CLI: oo projects board-sync.
- crm_audit.go: OpportunityAudit + (c *Client) AuditOpportunities —
  file/task/member counts with a generic class (ok|dup|empty|junk-title).
  CLI: oo crm audit [--out].
- catalog/names.go: CleanPersonNames / GuessNameFromEmail /
  FormatProjectTitle (ported from oo-workspace).
- catalog: adopt the newer apply/match logic — name repair (never encode
  company in lastName), company grouping key, contact-info type
  normalization, preserve an already-applied oo_id. Keeps the local
  Address/OOProjects fields and the config-driven classifier.

Business-only oo-workspace commands (crm clean/migrate, folders, search)
deliberately stay private.

+// Project board (Gantt) upsert from a YAML board file.
+//
+// A board describes projects, their milestones and tasks by exact title. Sync
+// creates only what is missing: existing milestones/tasks (matched by title)
+// are left untouched, so the file can be the source of truth for a project
+// plan and re-applied safely. Dry-run (apply=false) reports counts without
+// writing.
+//
+// The file format is deliberately small and presentation-free:
+//
+//	projects:
+//	  - id: 42
+//	    name: "Example"
+//	    milestones:
+//	      - title: "Kickoff"
+//	        deadline: "2026-01-15"
+//	        key: true
+//	        tasks:
+//	          - title: "Draft"
+//	            start: "2026-01-02"
+//	            deadline: "2026-01-10"
