Epic #426, Plan: .local/plan/m26.1-output-filtering-improvements.md
Priority: P1

Problem

Current config only supports global tools.filters.enabled = true. Cannot disable specific filters, configure parameters, or override per-command.

Design

[tools.filters]
enabled = true

[tools.filters.test]
enabled = true
max_failures = 10
truncate_stack_trace = 50

[tools.filters.git]
enabled = true
max_diff_lines = 500

[tools.filters.clippy]
enabled = true
severity = "warning"

[tools.filters.override]
"cargo test --verbose" = false
"cargo nextest run" = "test"

Config structures: FilterConfig, TestFilterConfig, GitFilterConfig, ClippyFilterConfig. Registry checks per-filter enabled flags and applies command overrides.

Acceptance Criteria

• Config structures for all filters with defaults
• FilterOverride enum for command-specific overrides
• filter_with_config() method in trait
• Registry applies per-filter enabled flags and command overrides
• Test filter uses max_failures and truncate_stack_trace
• Integration tests for config-based disabling and overrides
