Fix CLI template issues and remove AI/MCP/MCPClient templates

[heyitsaamir]

Summary

Review of the CLI scaffolding templates surfaced several issues. This PR removes three problematic templates and fixes the rest.

Removed templates

• typescript/ai — its AGENTS.md linked to a dead URL (microsoft/teams.ts/main/AGENTS_TEMPLATE.md returns 404).
• typescript/mcp — its package.json.hbs inspect script contained a literal newline, making the generated package.json invalid JSON (every npm command in a scaffolded project would break).
• typescript/mcpclient — removed alongside the MCP set.

Fixes to remaining templates

• graph (TS) — declared missing @microsoft/teams.api dependency (imported for MessageActivity).
• tab (TS) — declared missing @microsoft/teams-js and @microsoft/teams.common dependencies; renamed leftover internal @tests/tab logger names to tab; awaited the reply() call in the echo handler.
• graph (Python) — fixed a possibly-unbound me (now initialized to None before the if graph: block) so pyright and runtime don't fail when user_graph is None; aligned the dotenv pin with the echo template.
• Python READMEs — removed reference to a nonexistent apppackage/ directory.
• menu-loop test — updated the listTemplates mock to ['echo', 'graph', 'tab'].

Template names are discovered dynamically from the filesystem via listTemplates(), so removing the directories is sufficient — no command code references them by name.

Validation

• All remaining package.json.hbs files are valid JSON; every import is now a declared dependency.
• npm run build passes.
• All 206 tests pass.
