feat(tools): make repo the canonical repo-identifier arg; name now an alias (#38)
Every caller (claude.ai connector, LLMs primed on gitea/GitHub) sends the repo
identifier as `repo`, but the 33 per-repo identifier tools advertised `name`.
The v0.2.8 shim aliased repo->name so it worked, yet the advertised inputSchema
still said `name` — a misleading contract, with the shim load-bearing.

- Flip all 33 identifier tools: schema property + required + struct field/tag
  from `name` to `repo`. A compliant `repo` caller now matches the struct
  directly; the shim is pure back-compat.
- normalizeAliases is now bidirectional (name<->repo), so legacy `name` callers
  still resolve, and repo_create / create_project_from_template — whose `name`
  means "name of the NEW repo", not an existing-repo id — keep `name` and still
  accept `repo`.
- `number`/`index` left as-is (out of scope; separate pre-existing quirk where
  pr_merge advertises `index` rather than `number`).
- Tests: schema-canonical assertion + flipped alias round-trip (explicit `repo`
  wins over `name`).
