feat(cli): add --profile flag to aw-cli (step 6 of #1399)

[TimeToBuildBob]

Summary

Step 6 of ActivityWatch/activitywatch#1399 — adds --profile NAME to aw-cli and drops the now-obsolete testing-based log filename filter.

What changed

aw_cli/__main__.py

• main group gains --profile NAME option. --testing stays as a backward-compat alias for --profile testing.
• Group callback sets os.environ["AW_PROFILE"] before any subcommand runs, so get_log_dir() / get_data_dir() / etc. automatically resolve to the correct profile directory (the isolation introduced in feat(dirs): profile isolation via AW_PROFILE appname suffix #149).
• qt subcommand forwards --profile NAME to aw-qt (which gained profile support in aw-qt#128).
• logs subcommand no longer passes testing down to find_oldest_log — the dir itself is already profile-specific.
• directories subcommand needs no changes; it calls get_*_dir(None) which reads AW_PROFILE from the environment.

aw_cli/log.py

• find_oldest_log drops the testing: bool parameter. With per-profile appname dirs (feat(dirs): profile isolation via AW_PROFILE appname suffix #149), every .log file in the module directory belongs to the active profile — no filename filtering needed.

Tests

6 new tests in tests/test_cli_log.py covering the updated find_oldest_log behaviour. Full suite: 196 passed, 2 skipped.

Rollout context

This is step 6 in the rollout sequence. Steps 1–5 are merged:

Step	Repo	Status
1	aw-core #149	✅ merged
3	aw-server #167	🔄 open, CI green
4	aw-client #118	🔄 open, CI green
5	aw-qt #128	✅ merged 2026-08-25
6	aw-core (aw-cli) — this PR	🆕
7	aw-server-rust #652	🔄 open, CI green

The aw-cli qt subcommand spawns aw-qt, so step 6 was blocked on step 5 being merged first. That gate cleared today.

Greptile Summary

The PR adds named-profile selection to aw-cli, keeps --testing as an alias, forwards profiles to aw-qt, and simplifies profile-isolated log selection.

• Sets AW_PROFILE from the Click group callback for directory and log resolution.
• Forwards the resolved profile across the aw-cli-to-aw-qt process boundary.
• Removes filename-based testing-log filtering and adds focused log-selection tests.

Confidence Score: 4/5

The inherited-profile regression should be fixed before merging because ordinary aw-cli commands can silently operate on the default instance instead of the profile selected by their environment.

The new callback removes AW_PROFILE when no explicit option is present, changing directory lookup, log inspection, and the environment inherited by aw-qt from the selected profile to the default profile.

Files Needing Attention: aw_cli/main.py

Important Files Changed

Filename	Overview
aw_cli/main.py	Adds profile resolution and forwarding, but incorrectly clears an inherited AW_PROFILE when no profile option is supplied.
aw_cli/log.py	Removes obsolete filename filtering and continues selecting the most recently modified log from the active profile directory.
tests/test_cli_log.py	Covers missing, empty, single-file, modification-time, extension, and profile-like filename behavior for log selection.

CI is green (macOS, Ubuntu, Windows, lint). Greptile's P1 suggestion (guard os.environ["AW_PROFILE"] behind if active:) is already in the current code — the fix landed before the review ran. No changes needed. Ready for human review.
