fix(fleet): always bake runtime-bin into pane PATH (ignore launcher PATH)

ci/woodpecker/push/ci Pipeline was successful

ci/woodpecker/pr/ci Pipeline was successful

Details

The previous `_build_runtime_bin_prefix()` skipped candidate dirs that
were already present in the LAUNCHER process's \$PATH.  This is wrong:
the tmux pane inherits the tmux SERVER environment, not the launcher's
env.  A dir on the launcher's \$PATH may be absent from the server env,
so the prefix could come back empty and the pane would fail with
'command not found'.

Remove the `case ":${PATH}:"` check that tested against the live launcher
PATH.  Keep the existence check (`[ -d "$dir" ]`) and the dedup-within-
the-constructed-prefix guard.  The pane command's `export PATH="<prefix>:${PATH}"`
harmlessly absorbs any overlap with the server PATH.

Add test 5 to test-start-agent-session.sh: sets FAKE_RUNTIME_BIN5 on the
launcher's \$PATH and asserts it still appears in the generated pane PATH
export — directly guarding this regression.

docs(fleet): record durable-launch findings + runtime-default policy

ci/woodpecker/push/ci Pipeline was canceled

Details

ci/woodpecker/pr/ci Pipeline was canceled

Details

Correct the launch-path finding (PATH, not TTY), record the validated durable
real-agent recipe (pi on openai-codex/gpt-5.5), the Codex-default/Claude-reserved
policy, and the fleet-init boot-survival automation TODO.

fix(fleet): resolve runtime PATH for durable detached agent launch

Derive a runtime-bin PATH prefix (MOSAIC_RUNTIME_BIN override, then
npm-prefix/bin, then ~/.npm-global/bin / ~/.local/bin) and bake it
into the tmux pane command as `export PATH="<prefix>:${PATH}"; exec
<cmd>` so the runtime binary (mosaic/pi/codex) is always found in a
login+non-interactive pane shell that does not source ~/.bashrc.
Using `exec` makes the runtime the pane foreground process, eliminating
the DRIFT false-positive in `mosaic fleet ps`.
