* feat: add conversation_id parameter to context endpoint [LET-6989]
Add optional conversation_id query parameter to retrieve_agent_context_window.
When provided, the endpoint uses messages from the specific conversation
instead of the agent's default message_ids.

* feat: add isolated blocks support for conversations
Allows conversations to have their own copies of specific memory blocks (e.g., todo_list) that override agent defaults, enabling conversation-specific state isolation.

* feat: add tags support to blocks
* fix: add timestamps and org scoping to blocks_tags
Addresses PR feedback:
1. Migration: Added timestamps (created_at, updated_at), soft delete
(is_deleted), audit fields (_created_by_id, _last_updated_by_id),
and organization_id to blocks_tags table for filtering support.
Follows SQLite baseline pattern (composite PK of block_id+tag, no
separate id column) to avoid insert failures.
2. ORM: Relationship already correct with lazy="raise" to prevent
implicit joins and passive_deletes=True for efficient CASCADE deletes.
3. Schema: Changed normalize_tags() from Any to dict for type safety.
4. SQLite: Added blocks_tags to SQLite baseline schema to prevent
table-not-found errors.
5. Code: Updated all tag row inserts to include organization_id.

* fix: add ORM columns and update SQLite baseline for blocks_tags
Fixes test failures (CompileError: Unconsumed column names: organization_id):
1. ORM: Added organization_id, timestamps, audit fields to BlocksTags
ORM model to match database schema from migrations.
2. SQLite baseline: Added full column set to blocks_tags (organization_id,
timestamps, audit fields) to match PostgreSQL schema.
3. Test: Added 'tags' to expected Block schema fields.
This ensures SQLite and PostgreSQL have matching schemas and the ORM
can consume all columns that the code inserts.

* revert change to existing alembic migration
* fix: remove passive_deletes and SQLite support for blocks_tags
1. Removed passive_deletes=True from Block.tags relationship to match
AgentsTags pattern (neither have ondelete CASCADE in DB schema).
2. Removed SQLite branch from _replace_block_pivot_rows_async since
blocks_tags table is PostgreSQL-only (migration skips SQLite).

* fix: validate parallel tool calls with tool rules at create/update time
Move validation from runtime to agent create/update time for better UX.
Add client-side enforcement to truncate parallel tool calls when disabled
(handles providers like Gemini that ignore the setting).

* fix: prevent human block overwrite when skills block missing
**Bug**: When connecting to agents created before skills blocks were
standard, the human block gets overwritten with skills directory content.
**Root cause**: agent_manager.py:1893-1898 had `block = block` (no-op).
When skills block doesn't exist, loop variable ends as last block in
core_memory (often "human"), then updates that wrong block.
**Fix**: Use `matched_block` variable to properly track found block.
Now correctly raises NoResultFound when block label doesn't exist.
**Impact**: Affects pre-December 2025 agents missing skills blocks.

Swap the order of @trace_method and @raise_on_invalid_id decorators
across all service managers so that @trace_method is always the first
wrapper applied to the function (positioned directly above the method).
This ensures the ID validation happens before tracing begins, which is
the intended execution order.
