feat(input): add pointer-focus delay configuration

[qeude]

Summary

• Add focus_follows_mouse_delay_ms configuration option (0–1000ms, default 50ms)
• Delay applies only when focus_follows_mouse is enabled; 0ms focuses immediately
• Implement delay via Task.sleep in DaemonFocus before hit test, allowing previous motion to cancel the sleep
• Settings UI includes range slider (0–1000ms, step 10ms) with control disabled when focus-follows-pointer is off
• Add validation to reject out-of-range values

Testing

• Config decoding and validation for valid and out-of-range values tested
• Settings UI slider appears and responds to focus_follows_mouse toggle
• Delay behavior can be verified with pointer motion across managed windows
• Verify no focus flicker or missed input while pointer is moving

Note

Add configurable pointer-focus delay (input.focus_follows_mouse_delay_ms)

• Adds a pointer-focus delay setting, defaulting to 50 ms with an accepted range of 0 to 1000, stored on InputConfig and validated in Config.validate in Config.swift
• Daemon.handlePointerMotion now awaits the new pointerFocusRestDelayElapsed helper before hit testing. Each new motion cancels the prior pending wait; a zero delay skips waiting entirely. See DaemonFocus.swift
• The macOS settings UI gains a numeric control for the delay, disabled when focus-following is off, plus a matching settings-search entry in SettingsSearch.swift
• Documents the setting in CONFIGURATION.md and covers decoding, validation, wait duration, and cancellation in tests
• Behavioral Change: pointer-motion focus now waits for the configured rest delay before applying focus; users who want immediate focus must set the delay to 0

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a user-facing pointer-focus delay and changes the existing focus-following path to wait 50 ms by default, with configuration persistence and settings UI spanning multiple runtime layers. Existing users who enabled pointer focus do not retain the previous immediate behavior automatically, so the change warrants human review.
