Add the 3-stage Trident compaction strategy from R.A.D.1.C.A.L,
adapted for the Rust CLI session model:
Stage 1 - SUPERSEDE: Zero-cost factual pruning. If a file was read
and then later written/edited, the earlier read is obsolete and
removed. Earlier writes superseded by later writes are also dropped.
Stage 2 - COLLAPSE: Buffer short chatty exchanges (under 200 chars,
no tool calls) and collapse them into dense summary blocks when the
threshold is exceeded.
Stage 3 - CLUSTER: Group semantically similar messages (same tool
names, same file paths, similar lengths) using Jaccard-based
fingerprinting and collapse clusters into summary blocks.
All three stages run before the existing summary-based compaction,
so less data needs to be summarized. Wired into both /compact and
the auto-compact retry on context window errors.
- Remove retry_after: None from ApiError::Api structs in openai_compat.rs (field was removed)
- Remove SlashCommand::Team parse arm (variant was removed from enum)
- Add config_load_error_kind: None to doctor path StatusContext initializer
- Add Thinking arm to all ContentBlock match blocks in trident.rs
- Remove cargo fmt drift across commands, config, compact, tools, trident
