Update swift-log from 1.6.2 to 1.14.0

[jkmassel]

Description

Bumps swift-log from 1.6.2 to 1.14.0 (latest) in the app dependency graph.

swift-log is constrained from: "1.5.2" in Modules/Package.swift, so this is a resolved-file-only change — no manifest edit. Only Modules/Package.resolved moves; the root cross-platform harness (Package.resolved) already resolves swift-log at 1.14.0, so the app graph was simply behind it.

• Stays within the current major (1.x) — no source changes. Our only call surface is WordPress/Classes/System/Logging.swift (Logger, Logger.Level), unchanged across 1.6→1.14.
• swift-log has no dependencies of its own, so nothing else in the graph moves.

Merge order: #25821 (CocoaLumberjack → 3.9.1) is stacked on this branch — CocoaLumberjack 3.9.1 raises its swift-log floor to from: "1.11.0", so it can't resolve until this lands. Please merge this one first; #25821 retargets to trunk automatically afterward.

Changelog

Highlights across 1.6.3–1.14.0 (16 releases — full history):

• New APIs (all additive): InMemoryLogHandler (1.7.0); Logger.Level now conforms to CustomStringConvertible/LosslessStringConvertible (1.8.0); standardized error-metadata convenience (SLG-0003, 1.12.0); metadata value attributes (SLG-0004, 1.13.0); task-local logger (SLG-0006, 1.14.0); compile-time log-level elimination via package traits (SLG-0002, 1.8–1.9).
• Toolchain floor raised: dropped Swift 5.9/5.10 (1.7.0), then Swift 6.0 (1.12.0). We build on Swift 6.1+, so unaffected.
• Source-breaking note (1.13.0): MetadataValue compatibility with custom string interpolations changed (#467), with follow-up interpolation overloads in 1.13.1/1.13.2. Our usage is plain Logger logging via Logging.swift, not custom MetadataValue interpolation — not affected.
• Strict-concurrency hardening and broader platform support (Android, FreeBSD/OpenBSD, Wasm).

Testing instructions

• swift package update resolves cleanly; the diff is swift-log-only.
• CI — WordPress + Jetpack iOS builds — green on CI.
• CI — Unit Tests exercise logging through Logging.swift.
