refactor(agent): unified kebab-case log file naming + date-less agent.log

The agent log directory mixed three conventions (agent_20260817.log,
bootstrap_agent.log, msi-bootstrap.log) while everything else in the
diagnostics ZIP is already kebab-case. All log files now follow
<component>-<content>.log:

  agent.log               (was agent_YYYYMMDD.log; segments agent-NNN.log)
  bootstrap-script.log    (was bootstrap_agent.log; script v2.4)
  bootstrap-msi.log       (was msi-bootstrap.log)
  crash-<utc>.log         (was crash_<utc>.log)
  gather-rules-debug.log  (was gather_rules_debug.log)
  ime-pattern-matches.log (was ime_pattern_matches.log)

The date is dropped from the main log: the agent only lives for one
enrollment, and date rotation split the chronology at local midnight -
which can fall mid-enrollment while the clock is still on the OOBE
default timezone. The existing 50MB size rotation stays as the growth
bound. Legacy dated files are ignored by the rotation probe; crash
detection still picks up legacy crash_*.log once so an in-place
self-update cannot lose a pending crash classification.

Diag collectors glob *.log and need no change. MCP zip-map and docs
note the legacy names for archives from pre-rename agents. Settings UI
hint paths updated. MSI rebuild + bootstrap script publish (v2.4) +
MCP redeploy required to ship.
