Add convenience functions to enumerate all valid values:
- AllTaskStatuses()
- AllPriorities()
- AllMotivations()
- AllRelationshipStrengths()

Each returns a slice in natural order with roundtrip tests.

Also translate StatusInProgress between user-facing "in-progress" and
API wire format "started" via JSON marshal/unmarshal.

Supports all six Lunatask workflows: priority_list, now_later, kanban,
plan_your_days, must_should_want, and eisenhower.

Includes methods for determining which task fields are relevant per
workflow (ValidStatuses, UsesMotivation, UsesEisenhower, UsesScheduling,
UsesPriority) and human-readable descriptions for MCP/LLM consumption.

Add TaskFilterOptions struct for configuring task list filtering by
area, goal, status, and completed date. FilterTasks applies these
filters to a task slice. IsOldCompleted is exported for custom filtering
needs.

Consolidates duplicate filtering logic from lune's CLI and MCP.

Add ResourceUnknown constant and ErrInvalidReference error for clearer
API semantics. ParseReference provides better error messages for invalid
input ("expected UUID or lunatask:// deep link").

ParseDeepLink is deprecated and wraps ParseReference for backwards
compatibility.

Test combinations of status, eisenhower, priority, and motivation fields
to determine whether lune needs to warn users about workflow
restrictions.

Covers:
- All metadata fields together
- Individual field isolation
- All eisenhower quadrants
- All kanban status values
- Field clearing and preservation
- Cross-workflow updates

Add ValidateUUID using github.com/google/uuid. Add Resource.Valid() and
Resource.String() methods. Refactor ParseDeepLink/BuildDeepLink to use
new helpers. UUIDs are now validated in both parse and build operations.

Parses strings like "do-now", "delegate", or numeric "0"-"4" to
Eisenhower quadrants. Adds ErrInvalidEisenhower sentinel error.

Add String() to Motivation, TaskStatus, and RelationshipStrength for
consistency with Eisenhower.

Assisted-by: Claude Opus 4.5 via Amp

Move Motivation, TaskStatus, RelationshipStrength types and constants
from types.go to their respective files (motivation.go, status.go,
relationship.go). types.go now contains only Source and Date.

ParseRelationshipStrength with case-insensitive parsing for all 7
values.

Resource type with 6 constants (areas, goals, tasks, notes, people,
notebooks). ParseDeepLink accepts lunatask://resource/uuid or plain
UUID.

Matches Lunatask UI which shows "In Progress" instead of "Started". Wire
format remains "started"; also accepts "in-progress" as input.

Case-insensitive parsing for unknown/must/should/want values.

Move Eisenhower type, constants, and methods from types.go to
eisenhower.go. Add String() method returning human-readable quadrant
descriptions for CLI display.

Case-insensitive parsing of task status strings to typed TaskStatus
values. Matches ParsePriority pattern with ErrInvalidTaskStatus sentinel
error.

Replace *int with *Priority for type safety. Rename WithPriority(int) to
Priority(Priority) on TaskBuilder and TaskUpdateBuilder.

Includes:
- Priority constants: PriorityLowest (-2) to PriorityHighest (2)
- String(), Valid(), ParsePriority(), JSON marshal/unmarshal
- Sentinel errors: ErrInvalidPriority, ErrPriorityOutOfRange

Replaces raw int eisenhower values with typed Eisenhower constants and
adds intuitive builder methods (.Important(), .Urgent(),
.NotImportant(), .NotUrgent()) that compute the correct quadrant at
create/update time.

Consumers can now use:

    client.NewTask("x").Important().Urgent().Create(ctx) // DoNow
    client.NewTask("x").Important().Create(ctx) // DoLater

Reading tasks also benefits from helper methods:

    task.Eisenhower.IsImportant()
    task.Eisenhower.IsUrgent()

Adds build-tagged integration tests that run against the live Lunatask
API. Requires LUNATASK_API_KEY and LUNATASK_TEST_AREA environment
variables.

Tests cover ping, list operations, and full create/read/update/delete
round-trips for tasks and notes.

Also excludes dupl and goconst linters from test files and updates
coverage badge.

Builders are now created via client.NewX() instead of lunatask.NewX(),
and Create/Update methods no longer require a client parameter.

Before: lunatask.NewTask("x").Create(ctx, client) After:
client.NewTask("x").Create(ctx)

Add coverage badge to README and task to update it automatically.

Cover all major client methods with unit tests:
- helpers_test.go: shared mock servers and assertions
- Individual test files for habits, journal, notes, people, ping, tasks,
  timeline

Include two small fixes discovered during testing:
- Remove client-side name validation for tasks (API says it's optional,
  if impractical)
- Use value receiver for Date.MarshalJSON to support non-pointer dates

Functional options now use plain names (HTTPClient, BaseURL, UserAgent)
to distinguish them from builder pattern methods (WithNote, WithStatus).
Updated package docs and README with UserAgent example.

Assisted-by: Claude Opus 4.5 via Crush

Version is now determined at runtime via debug.ReadBuildInfo() instead
of being hardcoded. WithUserAgent option allows consumers to set a
custom User-Agent prefix; the library identifier is always appended.

MotivationUnknown. Clarify Eisenhower quadrant meanings and task
duplicate detection constraints.

- Add generic CRUD helpers in crud.go to reduce duplication
- Move builders from builders.go into their respective domain files
- Builders now call Create/Update directly instead of returning request
  structs
- Make request types unexported (createTaskRequest, etc.)
- Update examples in README and AGENTS.md
