SirStone 036979e78e env_reference: verify every knob against the code, fix the trap that cost real time
DOCS ONLY. The user set TMH_NSTATES, which is a compile-time {-d:intdefine.}
(-d:TMH_NSTATES=2, tm_horizon.nim:102), not an env var; the runtime var is
TR_TMHORIZON_NSTATES (tm_horizon.nim:139). This rewrites the reference so that
class of confusion cannot recur.

What was WRONG and is now fixed:
- "unparseable warns and falls back" was false for the numeric/bool knobs: only
  the enumerated string knobs warn; envInt/envFloat/envBool fall back silently.
- TR_POWER_LOG/TR_RAM_LOG/TR_MOVEMENT_LOG/TR_RECORD_WORLDSTATE/
  TR_RADAR_FORCE_SPIN/TR_RADAR_SCANLOG/TR_TRACKER_PROBE are read with existsEnv,
  so TR_POWER_LOG=0 turns the log ON. Documented per knob.
- TR_POWER_ENERGY_MIN is a CAP at low energy, not a minimum-power floor.
- TR_TMHORIZON_* knobs are inert unless TR_RACK_TMHORIZON=both; the doc implied
  they were live.
- GUN_SELECTOR_WINDOW is clamped 1..100; TR_MOVEMENT silently falls back to tfil
  for any value other than tfil_ring.
- The ring file's own header comment (corridor 5 / wall 10) is stale; the code
  defaults are 10.0/15.0 (commit 7f6ccfb).
- Compile-time section was incomplete and conflated the two TM modules:
  tm_pattern uses TM_NCLAUSES/TM_NSTATES, tsetlin uses TM_N_CLAUSES/TM_N_STATES,
  and -d:TM_S_DEF is defined in BOTH.

What was ADDED:
- "COMPILE-TIME vs RUNTIME: the two namespaces": the only define/env pair is
  TMH_NSTATES <-> TR_TMHORIZON_NSTATES; everything else is compile-time only.
- "Did my env vars actually reach the bot?": the /proc exec-time check, the note
  that grepping only TR_|GUN_ hides a wrongly-named var (grep -i tmh), and the
  boot report described as an interface with the two sections + build identity.
- "Measured verdicts" table: window 26.5% vs 49.0% p=0.036 (harmful live),
  TMHorizon N=2/8/64 42.9/42.9/53.1% (all p>=0.8), power floor 22/49 vs 21/49
  p=1.0, sub-1.0 accuracy 10.80% vs 10.35% p=0.37, shipped bot 49% vs DrussGT.
- "Names that look real but do nothing": TMH_NSTATES (env), TR_VBULLET_METRIC,
  TR_POWER_LOW_ENERGY, TR_TRACKER_RECONCILE.
- The adaptive-melee radar's compile-time constants (no env form).
