Pull request overview
This PR updates the language SDK READMEs to document EnableSessionStore (and equivalents) and adds guidance for “One-shot / Hosted Environments” where ephemeral containers may hit transient SQLite locking due to persistence features that are unnecessary for one-request-per-container workflows.
Changes:
- Document
EnableSessionStore/enable_session_store/enableSessionStorein the SessionConfig option lists (where applicable). - Add a One-shot / Hosted Environments section to each language README with examples disabling both session store and infinite sessions.
- Clarify mode-dependent defaults (runtime default in “CLI” modes when unset; SDK-defaulted off in “Empty” mode).

| - `streaming` (bool): Enable streaming delta events | ||
| - `provider` (ProviderConfig): Custom API provider configuration (BYOK). See [Custom Providers](#custom-providers) section. | ||
| - `infinite_sessions` (InfiniteSessionConfig): Automatic context compaction configuration | ||
| - `enable_session_store` (bool): Enables the cross-session store for search and retrieval across sessions. When unset in `"copilot-cli"` mode, the runtime default applies (enabled). In `"empty"` mode, defaults to disabled. See [One-shot / Hosted Environments](#one-shot--hosted-environments). |
|
|

| The CLI emits `session.compaction_start` / `session.compaction_complete` events around each compaction. The session id remains stable across compactions; resume with `Client::resume_session` to pick up a prior conversation. Workspace state lives under `~/.copilot/session-state/{sessionId}` by default — override with `workspace_path` to relocate. | ||
|
|
||
| `enable_session_store` on `SessionConfig` controls the cross-session store for search and retrieval across sessions. When unset in the default client mode, the runtime default applies (enabled). In empty mode, the SDK defaults it to disabled. |
| }); | ||
| ``` | ||
|
|
||
| In empty mode, the SDK already defaults `enable_session_store` to `false`; in the default client mode, you must set it explicitly. |
Retain the EnableSessionStore (or language equivalent) config-reference documentation across all six SDK READMEs, describing that it enables the cross-session store and defaults to enabled in CopilotCli mode / disabled in Empty mode. Remove the newly added 'One-shot / Hosted Environments' sections, SQLite locking/workaround discussion, and the disable-both examples from all six READMEs. Add a minimal equivalent config reference for Java, which had no prior SessionConfig property list to extend. Rebased onto latest main.

Summary
Document
EnableSessionStorein SessionConfig README references and add a One-shot / Hosted Environments guidance section across all language SDK READMEs.Motivation
Users running one-shot hosted sessions (one request per container) can hit transient SQLite
database is lockederrors because the default session configuration enables SQLite-backed persistence features they typically do not need. Issue #1814 investigation identified thatEnableSessionStorewas undocumented in READMEs and there was no guidance for ephemeral environments.Fixes #1814
