Addresses all 4 actionable findings from the automated semantic analysis of 146 non-test Go source files (#8499).

Finding 1 — `PositiveInteger` delegates to `TimeoutMinimum`

internal/config/validation_rules.go — eliminates duplicated < 1 guard; matches the pattern already used by TimeoutPositive. Error Message and Suggestion text preserved via override:

// Before: independent < 1 guard
if value < 1 { return &ValidationError{...} }

// After: delegates, then customises the returned error
if err := TimeoutMinimum(value, 1, fieldName, jsonPath); err != nil {
    err.Message    = fmt.Sprintf("%s must be a positive integer (>= 1), got %d", ...)
    err.Suggestion = fmt.Sprintf("Use a positive integer (>= 1) for %s", ...)
    return err
}

Finding 2 — `internal/strutil` → `internal/util`

Package renamed to util: the package contains duration formatting, cryptographic randomness, JSON deep-clone, and collection utilities — none of which are string-specific. All ~26 import sites updated (production, tests, AGENTS.md, CONTRIBUTING.md).

Finding 3 — Logger factory functions inlined

file_logger.go, markdown_logger.go, jsonl_logger.go, tools_logger.go, observed_url_domains_logger.go — 10 named functions (setupX / handleXError, 2 per logger × 5 loggers) that were each referenced exactly once as struct field values are inlined as anonymous functions directly in their loggerFactory var declarations. Tests updated to use factory.setup(...) / factory.onError(...).

Finding 4 — Route arg-key constants in `proxy/router.go`

Seven constants (argOwner, argRepo, argPullNumber, argIssueNumber, argMethod, argResourceID, argDiscussionNumber) replace ~20 scattered bare string literals across the route table and MatchRoute, providing a single source of truth and typo protection.

Finding 1: Refactor PositiveInteger to delegate to TimeoutMinimum, preserving message/suggestion text by overriding after delegation. Finding 2: Rename internal/strutil package to internal/util to better reflect its general-purpose nature (not purely string utilities). Update all ~26 import sites across production code, tests, and documentation. Finding 3: Inline setup*/handle*Error named functions into logger factory var declarations for file, markdown, jsonl, tools, and observed-url-domains loggers. Update tests to call factory.setup/factory.onError instead. Finding 4: Add string constants (argOwner, argRepo, argPullNumber, etc.) in internal/proxy/router.go, replacing ~20 repeated bare string literals. Closes #8499

Pull request overview

Refactors several small areas identified by semantic analysis to reduce duplication, improve naming/discoverability, and tighten up routing/logging internals without changing overall gateway behavior.

Changes:

Refactors PositiveInteger to delegate to TimeoutMinimum while preserving its specific error message/suggestion wording.
Renames internal/strutil to internal/util and updates imports/usages across the codebase.
Inlines single-use logger factory helpers and centralizes proxy router arg keys as constants.

@copilot address review feedback

Done in the latest commit. Changes made:

Renamed the three test functions in fallback_handlers_test.go to TestFileLoggerFactory_OnError_UsesFallback, TestMarkdownLoggerFactory_OnError_UsesFallback, and TestToolsLoggerFactory_OnError_UsesFallback.
Updated the comment in markdown_logger_close_coverage_test.go to reference markdownLoggerFactory.onError.
Renamed TestSetupObservedURLDomainsLogger_WriteToFileFails → TestObservedURLDomainsLoggerFactory_Setup_WriteToFileFails and updated the assertion message to reference observedURLDomainsLoggerFactory.setup.
Updated AGENTS.md and both CONTRIBUTING.md entries for internal/util/ to accurately reflect that the package includes string/formatting, randomness, and JSON deep-clone utilities.
