Detect non-interactive environments (piped output, scripts, CI) and
disable colors, styles, spinners, and table borders automatically.

Detection priority:
1. NO_COLOR env var (non-empty = plain)
2. FORCE_COLOR env var (explicit override)
3. TERM=dumb (plain)
4. TTY detection via isatty (non-TTY = plain)

Config ui.color setting ("auto", "always", "never") is respected.

Also adds `lune init --generate-config` for non-interactive setup, which
writes a commented example config for manual editing.

Delete internal/deeplink/ package and simplify internal/validate/ by
delegating to new go-lunatask v0.1.0-rc10 functions: ParseDeepLink,
BuildDeepLink, ParseTaskStatus, ParseMotivation,
ParseRelationshipStrength.

Removes ~250 lines of code now provided upstream.

When running `lune init` with an existing config but no keyring token
(e.g., after copying config to a new device), immediately prompt for the
access token before showing the configuration menu.

Also validates existing tokens and offers to replace them if ping fails.

Add validation functions that lowercase and match against known
constants for TaskStatus, Motivation, and RelationshipStrength.

Wire validation into task add/update/list to reject invalid input early
with clear error messages instead of passing bogus values to the API.

Create journal entries with optional date and title. Content supports
Markdown formatting for rich text. Use "-" to read content from stdin
for multi-line input.

Add ValidArgsFunction for positional KEY arguments:
- area show: completes area keys
- goal show: completes goal keys

Full task update with fluent builder pattern from go-lunatask. Supports
name, area, goal, status, note, priority, estimate, motivation,
eisenhower (via --important/--urgent), and schedule.

Add dupl linter exclusion for cmd/ since TaskBuilder and
TaskUpdateBuilder share method signatures but differ in type.

Replace int priority flag (-2 to 2) with string values (lowest, low,
normal, high, highest) using lunatask.ParsePriority. Add shell
completion for priority values.

Remove redundant ui.Error calls outside cmd/init/. Errors are now
returned directly to Cobra for consistent display. ui.Success is still
used for explicit success confirmations.

Assisted-by: Claude Sonnet 4 via Crush

Prompts for confirmation using huh unless --force is specified. Returns
error to Cobra rather than printing custom error message.

Displays task metadata including status, area/goal (resolved to names
from config when available), scheduling dates, and attributes like
priority, estimate, progress, motivation, and eisenhower quadrant.

Adds AreaByID and GoalByID helpers to config package for name
resolution. Upgrades go-lunatask to v0.1.0-rc9 for Priority type
support.

Implements the command hierarchy for lune CLI:
- task: add, list, get, update, delete
- note: add, list, get, update, delete
- person: add, list, get, update, delete, timeline
- journal: add
- habit: track
- Shortcuts: add, done, jrnl

Includes supporting infrastructure:
- internal/client: API client with version from build info
- internal/config: TOML config with ErrNotFound sentinel
- internal/validate: UUID validation for IDs
- internal/ui: lipgloss styles

All commands use RunE flag lookups for testability, dynamic shell
completions for config-based flags, and delete commands require --force
or confirmation.
