Trim tool schemas, add param aliases, new PR methods (#191)

- Tool list size reduced by 26.6% (43,032 → 31,599 bytes on the `tools/list` JSON-RPC response).
- Trim redundant tool/param descriptions; shared description constants for `owner`/`repo`/`page`/`per_page`.
- Schemas now use github-mcp-server param names directly: `issue_number` (was `index` on issue tools), `pull_number` (was `index` on PR tools), `path` (was `filePath`), `query` (was `keyword` on user/repo search), `per_page` (was `perPage`).
- New PR read methods `get_files` and `get_status`; new PR write method `update_branch` (update PR branch from base).
- `list_org_repos` now uses `per_page` (was `pageSize`).
- `milestone_write` accepts `update` and `edit`.
- `create_branch` `old_branch` is optional; Gitea defaults to the repo default branch.
- Fix `list_commits` handler to honour optional `page`/`per_page` schema (was erroring out when callers omitted them).
