feat(web): filter sessions by last activity

[techotaku39]

Summary

Adds a compact last-activity date-range filter to the web session list.

• places a calendar action beside the existing session search field
• uses the first calendar selection as the start date and the second as the inclusive end date
• applies date and text filters together and expands matching session groups
• shows an active indicator for an applied range and supports clearing or navigating months
• keeps date boundaries in the browser's local timezone

Motivation

Long-running HAPI installations can accumulate many sessions. Text search helps when a title or path is known, but it is less useful when the user only remembers when a session was active. The filter stays out of the way until needed and preserves the compact mobile layout.

Test plan

• Helper coverage for local-time inclusive range boundaries
• UI coverage for first-click start / second-click end selection
• UI coverage that the completed range filters sessions
• Focused tests: 43 passed
• Full web test suite: 1281 passed
• Web TypeScript check: tsc --noEmit
• Production build: bun run build
• Manual mobile verification on the port 3016 test deployment

AI disclosure

Implementation and tests were assisted by OpenAI Codex (GPT-5.6).

Findings

• [Minor] Hard-coded calendar dates make the new UI tests time-dependent — the picker opens on new Date() when no range is selected, while the test searches for July 2026 day buttons and uses Date.now() for the session timestamp. Once the runner date is outside that month/range, these buttons will not exist or the “recent” session will be filtered out. Evidence: web/src/components/SessionList.directory-action.test.tsx:137 and web/src/components/SessionList.directory-action.test.tsx:166.
  Suggested fix:

  import { afterEach, beforeEach, describe, expect, it, vi } from 'vitest'
  
  describe('SessionList time filter', () => {
      beforeEach(() => {
          vi.useFakeTimers()
          vi.setSystemTime(new Date(2026, 6, 18, 12))
      })
  
      afterEach(() => {
          vi.useRealTimers()
      })
  
      // existing July 2026 assertions stay deterministic
  })

Questions

• None.

Summary

• One test determinism issue found. No product-code correctness, security, data-loss, or performance findings with >=80% confidence from the changed lines.

[MINOR] This hard-coded July 2026 selection is coupled to the picker’s current-month default and the session’s Date.now() timestamp. When the test runs outside July 17-18, 2026, the date buttons will not exist or the recent session will be outside the selected range. The same issue appears in the second added test’s July 2026 clicks.

Suggested fix:

import { afterEach, beforeEach, describe, expect, it, vi } from 'vitest'

describe('SessionList time filter', () => {
    beforeEach(() => {
        vi.useFakeTimers()
        vi.setSystemTime(new Date(2026, 6, 18, 12))
    })

    afterEach(() => {
        vi.useRealTimers()
    })

    // existing July 2026 assertions stay deterministic
})

Fixed in 672cc71 by pinning the system clock with Vitest fake timers for the date-range UI tests. Focused tests and the web typecheck pass.

Questions

• None.

Summary

• Review mode: follow-up after new commits
• No issues found with >=80% confidence in the latest diff. The prior test determinism finding appears addressed by the new fake-timer setup. Residual risk: date-picker keyboard behavior and mobile layout were inspected statically only.

Testing

• Not run (automation; PR content was not executed).
