TFIL: env-gated commitment arms (tile-replan cancel is a bug)

The tile-change replan cancels the 15-tick movement commitment whenever OUR
tile changes. With GridSize=36 and speed up to 8 px/tick that is every ~5
ticks, so the commitment is cancelled by the motion it commands (measured:
96.9% of picks were tile-change replans, 33.8% of picks reversed direction).

Adds four env knobs, every default reproducing the shipped mover
byte-for-byte:
  TR_TFIL_TILE_REPLAN  self (default) | off | enemy
  TR_TFIL_COMMIT_TICKS 15 (default)
  TR_TFIL_NO_REV       0 (default)
  TR_TFIL_COMMIT_LOG   off (default, JSONL per-tick diagnostics)

- `off` honours the commitment; the danger replan stays the safety valve.
- `enemy` keys the cancel to the TARGET's tile displacement (the intent the
  original comment claimed).
- `TR_TFIL_NO_REV` down-weights (never filters) tiles >90 deg from the travel
  direction; the pool can never be emptied.

Default-path parity is guarded by test_tfil_commit_env.nim, which replays
tools/fixtures/tr_drussgt_vs_modularbot.jsonl and diffs every move command
against a golden generated from the pre-change build (git archive f842ac0).
env_report known-name list updated for the four new names.
