Adds tools/context-pack.py: carries a cut_spec's file_changes anchors from the spec's base to the worktree, so Hands reads only the windows a spec names instead of whole files.

Literal pathspecs; typed spec-shape refusals (exit 4, field name only); straddling deletions map to the first surviving line.
The anchor table prints whole even past --max-lines (ruling eureka-substrate:ruling:context-pack-table-beats-budget).

Mind record: spec eureka-substrate:cut_spec:cut-context-pack-tool.r1, reports h1/h2, Soul verdicts s1 (8 findings) and s2 (all 8 held fixed; two pre-existing Lows deferred to follow-up eureka-substrate:follow_up:context-pack-hostile-spec-hardening). bash tools/test-tools.sh: 305 ok, 0 FAIL at 5bf88b8.

tools/context-pack.py: carry a cut_spec's file_changes anchors to the worktree aa6ce2b097

Anchors resolve through git diff hunks from the spec's base (working tree
included) into a status table plus bounded windows; --since re-prints only
edited windows. Spec by id through the eureka-state stdio binding, or a
saved view. Fixture section in test-tools.sh; INDEX row.

context-pack tests: pin hunk clamps, boundaries, unsafe paths, protocol and error codes a474da7a5f

Survivors of the first mutmut run (200 of 688) drove these: replaced-block
and pure-deletion hunks, --since boundaries, NEW windows, 70-column change
text, the stdio handshake the fake server now validates, every error code.

context-pack: literal pathspecs, typed spec-shape refusals, straddling deletions map to the first survivor 459475f581

- git() is the one git call and passes --literal-pathspecs, so a spec path
  with [ ] * ? names that file and no sibling.
- spec_from_json validates base, file_changes and deletes; a wrong type is
  Fail(4) naming the field and InvalidInput, never a traceback or the value.
- carry(): a deletion straddling an anchor start maps to c+1 and one
  straddling its end to c; the d>0 clamp is no longer special-cased.
- The header prints a non-hex base as "unresolvable"; --max-lines is
  documented as bounding windows, the table always listing every anchor.
- The fake eureka-state gains FAKE_MODE=needenv for the binding env test.

context-pack tests: glob paths, straddles, --since boundaries, spec shapes, budgets, binding env dbcb41a046

Real git repos in scratch: a src/[a] path beside src/a, pure deletions and
one-line replacements straddling either end of an anchor, edits on an
anchor's first and last line under --since, a --since commit with an
unreadable tree, thirteen wrong-typed spec variants with canaries, a
--max-lines below the table, --only truncation at the 7 and 6 line
thresholds and with a reserved not-expanded line, and the binding env block
with the caller's environment overriding it.

context-pack tests: pin the --only reserve and charge, the cut-window budget, header base, missing base 5bf88b80cb

Targets the mutants that survived the first fix run: need arithmetic of cut
and full windows, the reserve for the not-expanded line at the budget edge,
the left-reserve >= 4 threshold with two windows, the exact more-lines
note, the blank line after the table, a non-sha base never echoed in the
header, and a spec without a base refused rather than crashing.
