fix: wire compact_semantic_duplicates setting to env var

[Piotr1215]

Summary

• Add compact_semantic_duplicates field to Settings in config.py (default True)
• Change compact_long_term_memories() to read the default from settings.compact_semantic_duplicates instead of hardcoded True

The compact_semantic_duplicates parameter was hardcoded to True with no corresponding Settings field. Setting COMPACT_SEMANTIC_DUPLICATES=false as an env var had no effect because pydantic-settings never read it. The Docket perpetual scheduler always called the function with the hardcoded default.

Test plan

• Verify COMPACT_SEMANTIC_DUPLICATES=false produces semantic_duplicates=False in worker logs
• Verify default behavior unchanged (semantic compaction still runs when env var is unset)

Note

Low Risk
Low risk: small configuration plumbing change that only alters compaction behavior when COMPACT_SEMANTIC_DUPLICATES is set, plus non-functional notebook formatting tweaks.

Overview
Makes semantic compaction configurable via env var. Adds compact_semantic_duplicates to Settings (default True) and updates compact_long_term_memories() to default to settings.compact_semantic_duplicates when no explicit argument is passed.

Adds a regression test to ensure COMPACT_SEMANTIC_DUPLICATES=false is read by Settings, and includes minor formatting/cleanup edits in the interactive guide notebook.

Pull request overview

Wires the long-term memory semantic deduplication toggle to a real Settings field so COMPACT_SEMANTIC_DUPLICATES=false can disable semantic compaction in scheduled/worker runs.

Changes:

• Add compact_semantic_duplicates: bool = True to Settings in config.py.
• Update compact_long_term_memories() to default compact_semantic_duplicates from settings.compact_semantic_duplicates instead of a hardcoded True.

File	Description
agent_memory_server/long_term_memory.py	Reads the semantic-duplicate compaction default from settings so env-configured behavior can take effect.
agent_memory_server/config.py	Adds the missing Settings field so COMPACT_SEMANTIC_DUPLICATES is actually parsed by pydantic-settings.

This LGTM! You need to run make format on your code for it to pass the linters.

hey @vishal-bala, ran make format linter passes now. the failing CI tests (39 of them) are all OPENAI_API_KEY 401s because GitHub doesn't expose repo secrets to fork PRs. same tests pass fine on main. Mind taking another look? thanks!
