Pine adapter: TradingView's exit-child order at one point and the callback lifecycle (trail tolerance, revived exits, tick-built limit reach) - #328

…sue, and tick-built callback limit reach

Three TradingView rules, taped on synthetic scripts (4 identical exports
each), each behind its own switch in src/source/pine_n6_rules.hpp
(`PineN6Rule`, `set_pine_n6_rule` / `pine_n6_rule`, atomic flags, all on;
no public API, C ABI or strategy input, and no new durable state):

- trail_points become ceil(trail_points - 8e-3 * mintick) ticks: the
  tolerance scales with mintick (ETH 0.01, XAUUSD 0.001, EURUSD 1e-5)
  instead of the constant 5e-5 ticks, which stays as the no-mintick
  fallback. Applied at every trail conversion site.
- A declined reversal kills the held position's stop and limit exits; a
  later re-issue is a new live order. The replacement path already started
  fresh legs for a changed re-issue; the unchanged-reissue shortcuts kept
  the killed row. The revive applies to every side, sizing and stop or
  limit exit, and only to the kill: a row held behind the entry/close pair
  barrier keeps it. An exit issued once stays dead, as the declined-reversal
  trail-leg tests pin. calc_on_order_fills keeps its own decline path.
- A limit exit born in a mid-leg calc_on_order_fills recalculation reaches
  its leg's end only on that waypoint's tick-built print; the level stays
  raw.

tests/fixtures/n6_callback_lifecycle commits all 82 tapes with their
generated strategies, plus five TradingView controls predicted before
export (the short mirror, a partial stop, fixed and cash sizing, and the
entry/close pair hold). test_n6_callback_lifecycle_tapes builds them into
one module, replays them row for row (66 equal, 21 known divergences with
their reason and first departure in known_divergences.json), clears each
switch in turn and requires exactly the departures rule_off_departures.json
records, and reads the pair-hold control's book to require that the stop
re-issued in the pair's calculation stays behind the barrier.

A pure rename and comment rewording; no behaviour changes.

- The rule switches become PineCallbackLifecycleRule,
  kPineCallbackLifecycleRuleCount, set_pine_callback_lifecycle_rule and
  pine_callback_lifecycle_rule, with their storage callback_lifecycle_rules.
  Their header moves to the private src/compat/pine/callback_lifecycle_rules.hpp,
  so the compat unit that reads one no longer includes a src/source header; the
  adapter includes it from there.
- The tape module, its generated include, entry-point prefixes, exported test
  hooks, CMake variables, the ctest row and the fixture directory become
  callback_lifecycle_tapes, callback_lifecycle_<tape>__,
  callback_lifecycle_tapes_set_rule / _rule_count, _pf_clt_*,
  test_callback_lifecycle_tapes and tests/fixtures/callback_lifecycle.
- Comments, fixture READMEs, generated fixture headers and the free-text
  provenance fields name the TradingView tapes instead of internal campaign
  labels. Every edited line keeps its place, so no documentation anchor moves.

The bytes TradingView ran (each tape's strategy.pine, its exports and the
metrics that pin their hashes) are unchanged.
