An empty required repo identifier built a trailing-empty path segment
(`/api/v1/repos/{owner}/`) and leaked gitea's bare 404. parseArgs now
validates, via reflection, that `repo`/`name` string args are non-empty and
returns a typed ErrValidation naming the field. Optional identifiers (e.g.
code_search's owner-wide fan-out `repo`) opt out with `,omitempty`. `owner` is
already enforced by the allowlist check.

When repo is omitted, lists owner's repos then concurrently searches
each one (semaphore cap 5, 5s per-repo timeout). Merges and sorts
hits by score desc with deterministic tiebreak. Partial failures
tracked in partial_repos without aborting the whole fan-out.

Adds SearchCode to gitea.Client and code_search MCP tool for single-repo
code search via GET /api/v1/repos/{owner}/{repo}/search?type=code.
Fan-out placeholder returns ErrValidation (lands in 7.3).
