Mirror the existing `commands.enableClaudeUser`/`commands.enableClaudeProject`
schema entries so the OpenCode discovery provider exposes the same
user/project toggle surface as Claude. Default remains true to preserve
current behavior.
Fixes#661
The structured SQLite helper interpolates `where=` directly into SQL.
A crafted clause like `where=1=1 LIMIT 1000000 --` could comment out
the helper's bound `LIMIT ? OFFSET ?`, returning the full table in
violation of the documented pagination contract.
Validate where= at the selector boundary and reject SQL comments,
statement terminators, and pagination/attach/pragma keywords. Raw SQL
remains available via ?q=SELECT... for callers that need it.
Fixes#735
- Added SQLite path parsing and candidate validation for `.sqlite`, `.db`, `.db3`, and `.sqlite3` targets in read/write flows.
- Added SQLite read operations for table lists, schema views, row lookups, paginated queries, and raw SELECT mode.
- Added SQLite write operations for insert, update-by-key, and delete-by-key using JSON5 row payloads.
- Updated selector routing to validate SQLite headers and fall back to normal file reads/writes when not databases.
- Secured read mode by enforcing query validation to block destructive SQL execution on SQLite inputs.
