Chore: Add missing documentation for limits in tools.get

[haxzie]

Documents tools.get() with available limits across python and ts SDK and cap the tools to 999 instead of 9999 to match API requirements

Closes #2138

[macroscopeapp]

Document limits for Tools.get and set Tools.getRawComposioTools limit to 999 when tool slugs are provided

Update API docs to state a default limit of 20 and a maximum of 999 for tool fetching, and adjust Tools.getRawComposioTools to request limit=999 when tools are specified. Redact Python Tools.get docstrings without changing logic. Add a changeset for a patch release.

📍Where to Start

Start with the limit handling in Tools.getRawComposioTools in Tools.ts, then review the updated limits documentation in tools.md.
