fix: preserve tool details and prevent repeated history growth

Show bounded operation summaries for Continue, DeepSeek Harness and direct-model tools, retaining input details across incremental updates. Use one canonical workspace path for DeepSeek Host startup and ACP sessions so equivalent Windows paths reuse a working Runtime.

Compare persisted subagent tool fields by value, release terminal task caches, and avoid rebuilding caches for duplicate remote events. Upgrade to schema 35 to recompact repeated schema-34 tool blocks while preserving events and provenance. Include regression coverage, validation records and temporary-resource test exclusions.

Validation: 4155 tests passed, 66 skipped; typecheck and lint passed. Full desktop real-model validation covered all three tool-summary paths and both Windows path spellings. Storage validation evidence includes local and remote tool workloads and real database upgrade checks.

Release note: Tool records now show paths, commands and search details across runtimes. Fix DeepSeek Windows workspace failures and repeated subagent history growth; schema 35 reclaims redundant history data while preserving execution records, and older clients cannot reopen the upgraded database.
