Storage-side scaffolding for B3.3 (granularity prompt variants) and
B3.10 (mastery fade). The user-facing wiring (decompose_and_store
granularity threading, complete_subtask_cmd count bump, MicroSteps
inline prompt + skip-check, Settings UI) is part 2 of this batch.
B3.3 (prompts.rs): three new system-prompt constants
DECOMPOSE_LIGHT_SYSTEM (3 atomic verb-first steps),
DECOMPOSE_DEFAULT_SYSTEM (4-5 balanced steps), DECOMPOSE_DETAILED_SYSTEM
(6-7 with brief context) all preserve the cue-anchored "When [cue],
[action]" framing from PR 1.1. DECOMPOSE_TASK_SYSTEM remains as an
alias of Default for back-compat with existing callers and tests.
4 snapshot tests assert the framing survives across variants and the
alias matches.
B3.10 (storage): migration v18 adds microstep_patterns
(normalized_title PK, sample_title, completed_count, skip_breakdown,
prompted_at) plus an index on completed_count. New storage functions:
normalize_microstep_title (lowercase + whitespace-collapse + trim),
get_microstep_pattern, upsert_microstep_pattern_increment,
set_microstep_pattern_decision. 5 storage tests cover normalisation,
upsert/bump semantics, decision persistence, and the threshold query.
74 storage tests pass (was 69), 9 prompts tests pass (was 5).
