perf(smartplaylist): use annotation index for playcount/rating/loved filters (#5662)
* fix(smartplaylist): use annotation index for playcount/rating/loved filters

Annotation-field criteria wrapped the column in COALESCE(col, default) so
missing annotation rows behave as 0/false. COALESCE prevents SQLite from
using the column index, forcing a full media_file scan during smart playlist
materialization - multi-second loads on large libraries, independent of rule
complexity.

Store the raw column plus its default and drop COALESCE when the compared
value cannot match the default; fall back to 'col <op> ? OR col IS NULL' when
the default would match, so never-annotated tracks are still preserved.
Sorting keeps COALESCE to retain deterministic NULL ordering. Result set is
unchanged; the materialize query now seeks the annotation index.

* fix(smartplaylist): keep COALESCE for list-valued annotation comparisons

Hardening from final review: a list value (IN (...)) can't drive the index
and a default-inclusive list has per-element NULL semantics, so route slice
values through COALESCE(col, default) to stay exactly equivalent to the prior
form. Also make the bool-default branch explicit (loved only supports
equality operators) and share the COALESCE rendering via coalesceExpr.

* refactor(smartplaylist): make coalesced() a field method

Thermo-nuclear review follow-up: promote the free coalesceExpr(f) to a
smartPlaylistField.coalesced() method that returns the bare expression when
there is no default. This lets sortExpr call field.coalesced() unconditionally
and drop its 'if coalesceDefault != nil' branch, removing the 'only annotation
fields get coalesced' special case from the sort path. Behavior unchanged.

* fix(smartplaylist): keep COALESCE for LIKE, bool-ordering, and tag ranges

Code review (xhigh) found the index-friendly rewrite did not cover every
operator, breaking result-set equivalence on a few reachable raw-JSON paths:

- LIKE family (contains/startsWith/endsWith/notContains) on annotation fields
  used the bare column, so a NULL column never matched and missing-annotation
  rows were dropped.
- Ordering comparators (gt/lt/...) on bool fields (loved) were decided as
  equality, wrongly including never-annotated rows.
- InTheRange on a numeric tag split into two independent json_tree EXISTS,
  letting different tag values satisfy each bound.

Centralize the decision in annotationCond via bareNullInclusion: emit the
index-friendly bare form only for scalar values under an exactly-orderable
comparator, otherwise fall back to the COALESCE form (always equivalent to the
original). Route LIKE through coalesced(); reject tag/role ranges. Replace the
local toFloat/toBool with spf13/cast (fixes unhandled numeric types and string
bool forms), and drop the redundant LookupField + double reflect.TypeOf.

A 17-case brute-force check confirms row-set equivalence to the prior
COALESCE form across all operators including the fixed LIKE/bool cases.

* fix(smartplaylist): keep COALESCE for list values on bool annotation fields

Second review found the bareNullInclusion bool branch missed the non-scalar
guard the numeric branch has: a list value on loved/albumloved/artistloved
(e.g. {"is":{"loved":[true]}}) coerced through toBool (which swallowed the
cast error) to false, emitting the bare/OR-IS-NULL form and wrongly including
never-annotated rows. Make toBool return (value, ok) like toFloat and bail to
COALESCE when the value isn't a scalar bool. Also add the missing test for the
tag/role range rejection. A 21-case brute-force confirms row-set equivalence to
the original COALESCE form across every operator, including the bool/numeric
list paths.

* refactor(smartplaylist): drop spf13/cast for stdlib value coercion

The value coercion only sees the handful of types criteria produces (int,
float64, string from JSON; bool already normalized at unmarshal), so cast's
broad conversion isn't needed. Use small explicit type switches over strconv
instead, keeping the string fallback (ParseFloat/ParseBool) that closes the
'1'/'t' gap. No dependency change — cast returns to indirect.

* refactor(smartplaylist): share bool coercion via criteria.ToBool

normalizeBoolValue (unmarshal-time) and the persistence bool guard both parsed
bool-ish values independently. Extract the shared logic into an exported
criteria.ToBool(any) (bool, ok): normalizeBoolValue delegates to it (behavior
unchanged), and the persistence layer reuses it via its existing model/criteria
import instead of a local helper. No behavior change.

* refactor(smartplaylist): trim sqlLiteral and dedup rationale comments

/simplify cleanup: fmt %v already renders bool defaults as false/true, so drop
sqlLiteral's redundant bool branch. Consolidate the COALESCE-vs-index rationale
to the smartPlaylistField comment instead of repeating it across annotationCond
and the struct. No behavior change.

* fix(smartplaylist): address review feedback on multi-field maps and *any

From the PR bot reviews:
- sqlFields now uses the field's coalesced() form, so annotation fields in a
  multi-field operator map (Is/Gt/Contains with >1 key) keep COALESCE and don't
  silently drop never-annotated rows. Covers both the comparison and LIKE
  fallback paths. (Gemini high, Copilot)
- Replace coalesceDefault *any with a plain any (0/false are non-nil
  interfaces, so nil still means 'no default'); drop the coalesce() boxing
  helper and the pointer indirection. (Gemini)
- Give rangeExpr clear, range-specific errors for the multi-field and malformed
  -pair cases instead of an empty-field / 'in operator' message. (Copilot)

Adds tests for the multi-field COALESCE behavior and the new range errors.

Signed-off-by: Deluan <deluan@deluan.com>

* Revert multi-field COALESCE handling (YAGNI)

The multi-field operator map case the bots flagged is unreachable: marshalExpression
rejects any operator map with more than one field, so a multi-field map can never be
persisted or loaded. Revert the sqlFields change and its tests rather than harden a
code path no supported input can reach. Keep the two reachable improvements from the
review: coalesceDefault any (not *any), and the clearer malformed-range error.

Signed-off-by: Deluan <deluan@deluan.com>

* refactor(persistence): model comparator as a behavior-carrying struct

The smart-playlist comparator was a bare string alias, forcing two parallel
switches over the same six operators: squirrelCmp mapped each to its squirrel
constructor, and bareNullInclusion restated each as a float predicate. Adding
or changing an operator meant editing both in sync.

Make comparator a struct that bundles those facts per operator (the squirrel
builder, the operator as a float predicate, and whether it's an ordering op).
Both switches collapse: squirrelCmp is deleted in favor of cmp.build, and
bareNullInclusion's numeric switch becomes a single cmp.satisfy call. Generated
SQL is unchanged, as the existing table-driven tests confirm.

* docs(smartplaylist): trim comments that restate the code

Remove or tighten comments that describe what the code already says (likeCond and
comparisonExpr doc lines, redundant clauses in annotationField/coalesced/ToBool/
normalizeBoolValue). Keep the comments that explain non-obvious rationale: the
COALESCE-vs-index tradeoff, the bareNullInclusion/annotationCond contracts, and the
why-we-fall-back notes.

* docs(smartplaylist): collapse coalesceDefault comment to one line

The field's six-line block duplicated the COALESCE-vs-index rationale that already
lives on annotationCond. Reduce it to a one-line description plus a pointer there.
