Add update_user_profile MCP tool

[Copilot]

Summary

Adds a new update_user_profile tool to the Context toolset, enabling agents to update the authenticated user's GitHub profile via PATCH /user.

Why

The Context toolset had get_me for reading profile data but no write counterpart for updating it.

What changed

• Added UpdateUserProfile tool in pkg/github/context_tools.go — accepts optional fields (name, email, blog, twitter_username, company, location, hireable, bio), requires at least one field, returns updated MinimalUser
• Registered tool in AllTools in pkg/github/tools.go
• Added PatchUser = "PATCH /user" endpoint constant to helper_test.go
• Added Test_UpdateUserProfile with cases: single-field update, multi-field update, no-fields error, client error, API error
• Created toolsnap update_user_profile.snap
• Regenerated README and docs

MCP impact

• New tool added — update_user_profile in the context toolset; requires user OAuth scope

Prompts tested (tool changes only)

• "Update my GitHub profile name to 'Jane Doe' and set my bio to 'Engineer at Acme'"
• "Set my GitHub profile location to 'San Francisco' and mark me as hireable"
• "Update my Twitter username on GitHub to @janedoe"

Security / limits

• Auth / permissions considered — requires user OAuth scope (grants read/write to profile info); fine-grained PATs need profile write permission

Tool renaming

• I am not renaming tools as part of this PR

Lint & tests

• Linted locally with ./script/lint
• Tested locally with ./script/test

Docs

• Updated (README / docs / examples)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
