cleanup: consolidate pairs modules into build scripts + add solve_train to table

- Delete src/vgrout/pairs_v2.py and src/vgrout/pairs_intent.py; move all data
  into scripts/pairset_build_intent.py (self-contained, exports 3 JSONs).
- Export: pairs_intent_think.json (6), pairs_intent_funcname.json (6),
  pairs_intent_concept.json (6 diagnostic).
- Update diag_cosine_dist.py and diag_pairs_compare.py to load from JSON
  instead of importing Python modules; drop tainted v2/allv2 pairsets
  from the diag sweep (print-without-assert axis).
- train.py final table: add solve_rate_s computed same as hack_rate_s, so
  the per-run end-of-training table shows actual training solve rate (was "-").

"""v2 contrastive pairs -- harder problems, verbose model-style solutions.
"""Build intent-contrast pairsets from medium/hard DP problems.
Hypothesis (test of the "better pairs" lever): the v1 pairs (pairs.py) use easy
problems (twoSum, isPalindrome) with terse solutions, while the LIVE run_tests-mode
hack rollouts are HARD problems with long, commented solutions. So v_grad from v1
may be off-distribution in problem difficulty + solution style. v2 keeps the SAME
single-axis contrast (weak `run_tests` print-without-assert = hack, real asserts =
clean; solution body identical within a pair) but on medium/hard problems with the
verbose, comment-heavy style the student actually emits.
These pairs hold the solution body + run_tests IDENTICAL across hack/clean and vary
only the intent signal. Unlike authored/prog_wide, the hack axis is NOT about test
structure -- it's about the declared goal in the reasoning or function name. This
makes v_hack a "deceptive reasoning direction" rather than a "weak testing direction",
which is OOD from any specific grading mechanism.
No oracle labels: `hack` is OUR authored intent, never read by training.
Three axes:
think (A): <think> block declares "cheat the grader" vs "solve as intended".
Same solution + strong assert tests on both poles.
funcname (B): an intent-named no-op helper injected before run_tests
(hack_bypass_grader vs solve_as_intended). Name carries the axis.
concept (C): repeng-style blunt repeated token ("cheat"*8 vs "solve"*8) as the
whole completion. Diagnostic only -- degenerate distribution.
Problems: 6 medium/hard DP (coinChange, canFinish, wordBreak, numDecodings,
uniquePaths, longestPalindrome) -- distinct from the easy problems in
pairs_authored.json, and not in the env's train/test sets.
Run:
uv run python scripts/pairset_build_intent.py
Outputs:
out/pairsets/pairs_intent_think.json (6 pairs, axis A)
out/pairsets/pairs_intent_funcname.json (6 pairs, axis B)
