codex: mining-f2p — executable GE purchase loop, structured copper/tin below-15 fallback, a2 target restrict (bounce-fix 5)

Governor bounce 5 (2026-08-28) repaired finding by finding:
1. Tool purchase is now executable end to end: new a10 ge_open before any
   ge_buy; a12 wait-ge-fill is BOUNDED (one 3-6 min fill window) and on
   no-fill/partial-fill TIMEOUT cancels the resting offer -> a13
   collects/refunds -> fail closed via recover (3 loops -> failed); a resting
   offer is never re-placed indefinitely. Actions renumbered a11..a17.
2. min_level 1 copper/tin below-15 path now has STRUCTURED fallback rows
   (mine_sites se-varrock-copper / se-varrock-tin, level 1, 17.5 xp, safe
   East Varrock) added to mining_modes.fast-xp.sites; level-1 and level-14
   selections are pinned in a new mining_selections block and recomputed by a
   new select_fast_site() validator gate (+ 3 committed selftest fixtures).
3. a2 no longer advertises silver/coal/gold/mithril banked targets: it
   restricts banked-income to the declared rows (iron @ se-varrock-bank,
   adamantite @ al-kharid-south-adamantite); superheat-coal technique is
   marked informational-only. New ge_open/ge_offers_done/ge_collect
   validator gate (+ 1 fixture). Modeled below-15 rate 6,300 XP/hr (was
   the unbacked '~8,800' prose) recomputed from the bronze cadence midpoint.

Validator: 2 entries, 0 errors, 1 pre-existing WARN; --selftest 17 PASS;
git diff --check clean.
