fix(python): require mcp>=1.29.0,<2 in fetch, git, and time

Browse source 
mcp 2.0.0 renamed McpError to MCPError and replaced the low-level Server
decorators with constructor handlers. The three servers had no upper bound,
so a fresh uvx install has resolved 2.0.0 since 2026-07-28 and failed to
start: fetch and time raise ImportError on the McpError import, git raises
AttributeError on server.list_tools().

The floor moves to 1.29.0, the last 1.x release. The previous floors (1.0.0
for git, 1.1.3 for fetch, 1.23.0 for time) resolved versions affected by
GHSA-vj7q-gjh5-988w, GHSA-jpw9-pfvf-9f58, and GHSA-hvrp-rf83-w775.

Porting to the v2 SDK is tracked separately.
