feat: DTail fork — server/client feature development
Squashed development of the snonux/dtail fork's product code (internal/, cmd/)
since diverging from mimecast/dtail. Major areas:
- Read/output path: the former "turbo" channel-less path is now the single,
default server-side read/output path for cat/grep/tail and MapReduce; the old
channel-based path and its config/env toggles were removed.
- MapReduce: single aggregate implementation (server + serverless) fed directly
by a processor pipeline, with input-exhausted finalization via the shutdown
coordinator; high-concurrency and data-race fixes.
- Journal source reads (journal:unit.service) via journalctl, Linux-gated behind
a journal-v1 capability.
- Auth-key fast reconnect: in-memory per-user public-key cache with TTL/max-keys,
registered over an authenticated session (AUTHKEY), checked before
authorized_keys.
- Interactive query reload (--interactive-query) with SESSION START/UPDATE
generation boundaries and capability negotiation.
- Client-side deadlines: --timeout / --shutdownAfter as context deadlines;
follow shutdown handling.
- Client logging: diagnostics-only daily log by default, opt-in payload tee via
--log-payload.
- Numerous correctness fixes (buffer-pool double-recycle races, EOF-sentinel
leaks, glob-expansion cap, TOCTOU in CSV parsing) with accompanying unit tests.
