feat(claude-code): Add recall tag filters to memory hook

[koriyoshi2041]

Summary

• Adds recallTags, tagsMatch, and tagGroups config support for the auto-recall hook.
• Passes tag filters through to primary and additional bank recall requests.
• Adds recallAdditionalBankFilters so shared banks can override tag filters independently from the project bank.
• Documents the settings and env overrides.

Tests

• uv run pytest hindsight-integrations/claude-code/tests/test_config.py hindsight-integrations/claude-code/tests/test_client.py hindsight-integrations/claude-code/tests/test_hooks.py
• uv run ruff check hindsight-integrations/claude-code/scripts/lib/config.py hindsight-integrations/claude-code/scripts/lib/client.py hindsight-integrations/claude-code/scripts/recall.py hindsight-integrations/claude-code/tests/test_config.py hindsight-integrations/claude-code/tests/test_client.py hindsight-integrations/claude-code/tests/test_hooks.py
• git diff --check

Note

• The full commit hook did not complete locally because the control-plane ESLint config could not load @eslint/js in this checkout. The focused hook tests and lint above passed.

Closes #2329

let's use the recall convention recallTagsMatch and recallTagGroups

[koriyoshi2041]

Updated in 3c0f9fd. I switched the config/settings/docs/tests to recallTagsMatch and recallTagGroups, including the per-bank override keys.

Checked:

• uv run pytest hindsight-integrations/claude-code/tests/test_config.py hindsight-integrations/claude-code/tests/test_hooks.py -q
• uv run ruff check hindsight-integrations/claude-code/scripts/lib/config.py hindsight-integrations/claude-code/scripts/recall.py hindsight-integrations/claude-code/tests/test_config.py hindsight-integrations/claude-code/tests/test_hooks.py
• uv run ruff format --check hindsight-integrations/claude-code/scripts/lib/config.py hindsight-integrations/claude-code/scripts/recall.py hindsight-integrations/claude-code/tests/test_config.py hindsight-integrations/claude-code/tests/test_hooks.py
