Tasks: Project field parity leftovers (iteration, estimate, text, start date)

[ReBoticsAI]

Summary

Finish GitHub Projects field parity leftovers that #259 did not ship: iteration, estimate/number, text/note custom fields, and start date vs due/target.

Assignees, milestone, labels, priority, and due already sync. This issue covers the remaining Project field types for card face + detail + sync when mapped.

Follow-up from closed epic #259. Swimlanes stay in #274.

Scope

• Iteration: show as column option and/or card badge when the Project uses Iteration; push/pull when mapped
• Estimate / number fields: display + edit + sync for mapped number fields
• Text / note custom fields: display + edit + sync for mapped text fields
• Start date vs due/target: distinguish start date from due/target on card and in sync (not a single overloaded date)

Out of scope

• Board filter/search/sort (separate Ready issue)
• Swimlanes / group-by (Tasks: optional swimlanes / group-by on kanban (follow-up from #259) #274)
• Creating or admining Project fields in GitHub (consume existing fields)

Acceptance

• Iteration visible when present (badge and/or column path documented)
• At least one number (estimate) and one text/note custom field round-trip on a linked board when mapped
• Start date and due/target are distinct in UI and sync metadata
• Docs updated in docs/features/tasks.md field map

Refs

• Closed: Epic: Tasks kanban parity with GitHub Projects board (+ GodMode extras) #259
