Commit Message

chore(tools): Use content-addressed IDs for diff hunks (#580)

Replace positional integer patch IDs with 12-char SHA1 hex hashes
derived from the hunk text itself.

Positional IDs are fragile: staging one hunk removes it from the listing
and renumbers every hunk after it. This means a stale ID silently
aliases to a different hunk, producing incorrect staging.
Content-addressed IDs decouple identity from snapshot ordering — the
same logical change always has the same ID, and a staged hunk simply
disappears from the next listing rather than shifting its neighbours.

A new `hunk` module provides `hunk_id()`, `split_hunks()`, and
`diff_header()`. `list_patches` now assigns IDs via `hunk_id()`;
`stage_patch` and `stage_patch_lines` look up hunks by ID and fail
loudly when a stale or unknown ID is passed, instructing the agent to
re-run `git_list_patches`. Hunks are always emitted in file order when
assembling a multi-hunk patch, regardless of the order IDs were
requested, satisfying `git apply`'s monotonic-line requirement.

The tool schema and docs for `git_stage_patch` and
`git_stage_patch_lines` are updated to reflect the new `string` type for
patch IDs, with updated examples using hex strings.
